Petroleum Engineer Career Training Guide

Question: How much money does a petroleum Engineer make? A petroleum Engineer who works in the Gulf for USA companies? I've always wanted to be a petroleum Engineer. Can any one tell me specifically how much a petroleum Engineer who graduates from USA universities makes. And travels to the Gulf and work there for the US companies. Will he succeed or no? will he make alot of money in the Gulf? please tell me exactly what are the positive and negative things about it?

Answer: I'll abbreviate Petroleum Engineer/Engineering as "PE" for sake of typing. PEs will get paid (base) between $65,000 and $200,000, depending on many things. The low end is for new grads (not a lot of openings for them right now, so maybe even less money). The upper end is for those with special skills and a LOT of experience. If they work on off-shore rigs, they get extra pay (>10% more). Downsides are that PEs are in a highly volatile industry - they spend a lot of time unemployed, so they have to save the big bucks for when they have no income. Also, the government is doing everything it can to discourage production and expansion of the domestic industry, so it's not growing. If you want to work in the Gulf area, contact the PE program at TAMU or U of Houston or UT-Austin, or maybe LSU. They can provide recent starting salaries and put a positive spin on things for you.

Question: What is the rate of employment in petroleum engineer technology? im interested to be an petroleum engineer technology but i was wondering what is the rate of the employment of it is worth doing it? and the average salary?

Answer: Virtually 100% employment. The only unemployed ones probably are only temporary between company changes and only stay that way as long as they want to. Yeah, it's worth doing it, if you're interested. I know guys that work for petroleum companies that have been bought and sold nearly a dozen times in 20 years. During the sale they might be out of a job for a few weeks but they're always reemployed by the new buyer. They make great salaries. I know a kid that went into Petroleum Engineering at Marietta College in Ohio three years ago, and last year he was making $30 an hour working for a petroleum company as a summer job. He got to do light travel and didn't have to be boxed up in a cubicle, he was managing small oil wells in Ohio. So not even being out of college he was making really great money. He was making more money than he was spending on college. Great deal, that. He'll graduate next spring with no student loans and no debt, and probably making $50,000 a year on the day he graduates.

Question: How much money does a petroleum engineer make in Kuwait: An Engineer who is from United states working in KUW? Just wondering how much would a petroleum engineer make in Kuwait who works for Unites states companies there. Is it worth it, I mean is it worth the hard work and traveling from USA to Kuwait??

Answer: my cosine work with the KOC company he is an engineer they give him maybe from 4000 KD to 5000 KD its about 14000 USD to 17000 thousand USD and don't forget the car they give him and they repair it for free if he damaged it and they give him latest mobile for free and free calls whatever it was even if it is 1000 USD also they give him free apartment but i don't recommended this because it is far away from the city but i don't know if this for Kuwaitis only or for all the engineers

Question: Scope of petroleum engineer in USA and worldwide? Is it a right choice to be a petroleum engineer, Looking it's future (next 2 decades) ?.....What is the scope of any other engineering discipline with good pay in USA and worldwide? Genuine source along with clear thoughts will be highly appreciated.

Answer: petroleum engineering is surely a very good field offering high pay scales.The talks that petroleum resources is declining has started some 30 years hence and still new petroleum resources are being discovered now and then.so no worry petroleum engineering is surely a safe and benefitial field to pursue.

Question: Chances of working as a Petroleum Engineer in US? Hi, What are the chances of working as a petroleum engineer in US or Canada. I mean is there a high demand for them or not? And how many years of oil are left for each of them? Also, i wanna know how much, on average, how does each of the following get: Petroleum Engineer Electrical Engineer Mechanical Engineer Please mention where u got the range for each. Thanks!

Answer: Petroleum engineers are in high demand in the US/Canada for one very important reason. The workforce at most petroleum companies is aging quickly, and the average age of engineers in those fields is higher than most fields. Petrochemical companies pay big money for new graduates, especially since they have to overcome the stigma of working for "big oil" that many new graduates perceive. In general, a petroleum engineer will get $60k-$80k starting in the US, an electrical engineer will get $50k-$70k and a mechanical engineer will generally get $50k-$70k also. There are always exceptions of course. This info is from the U.S. Bureau of Labor Statistics. However, in general, petroleum engineers don't have as many opportunities for advancement as the other two, so while their starting salaries are high, it is not out of the ordinary for an ME or EE to eventually pass the PE up later in their careers.

Question: What would you choose: pharmacist or petroleum engineer? If you have to start all over again, which career would you choose: pharmacy or petroleum engineering. Pharmacy requires money to go to pharmacy school and longer education while petroleum engineering requires you to work where the oil is and may be in decline in the future when oil runs out. Assume that you are living in the US.

Answer: im pretty sure that right now that the US is in high demand for some petroleum engineer. it's a lil risky but if something happens you could be living the good life. but pharmacy is a safer way to make money

Question: Can you become a petroleum engineer with a chemical engineering degree? Is it possible? Or do you have to get a degree in Petroleum engineering?

Answer: Yes you can specialize in petroleum with a chem eng degree. Some schools also have petroleum engineering course.

Question: Petroleum Engineer????? Is it hard to become one? How many years? Do you have to study alot and take a test?

Answer: 1.You'd study mechanical engineering, chemical engineering, or petroleum engineering (not offered at most shools). Those are BS degrees so 4 years of school. 2.You'd make a lot of money (~$75k starting) 3.You'd most likely work in texas, alaska, or california, and you might even work on an offshore platform where you would be isolated for long periods of time. You might work overseas in saudi arabia, or kuwait. 4.You'd have a very dangerous job as petroleum is a combustible chemical. People DIE at work, no joke... 5.You'd have a relatively short career as API estimates oil will run dry by 2057... Probably better to study to be a chemical engineer and be a little more versatile...

Question: Is it a good time to become a petroleum engineer? I wanna if you think this time is a good time for one to become a petroleum engineer or is it too big of a risk to take? Also, do you think the risk is worth taking...is the job rewarding? Is there a chance that oil is gone (i mean all over the world) or is it too early for that? Any help is highly appreciated! Thanks.

Answer: Yes! It's a good time. There are up and down times in all industries, but it's a real good career.

Question: What exactly is involved in a life as a petroleum engineer? Hello. I'm currently a freshman at Penn State, and am considering changing majors. Petroleum engineering has caught my interest although the lifestyle could be a bit of a concern. I know pay is great, but I want to live a happy life as well haha. So is there anyone who could give me some good information on the career? Thank you!!

Answer: The working conditions and locations for petroleum engineers are pretty much the same as those of many other engineering disciplines. There can be some field work but there can also be a good deal of office work. The work loads and hours are also similar. People typically get false ideas about the various engineering disciplines. They think mechanical engineers only deal with engines and rotating equipment, civil engineers only do construction work and petroleum engineers spend their time in the oil field with a hard hat and boots. That is just not the case.

Question: How much money would a petroleum Engineer make if he works in U.A.E? To be specific, a person working in Dubai? I'm becoming a petroleum Engineer. please tell me about this, a petroleum Engineer who works in Dubai. would that be a good job? would i make more money there then working in USA? what's the salary for a petroleum Engineer who works in Dubai? i would appreciate anyone who would tell me about this and answers my questions. Thanks!! I'm PhD Engineer

Answer: well...if you were working for an american company in dubai, the average is 108000 a year...

Question: What possibie Project/Paper presentation topics can you suggest for me as a Petroleum Engineer? I am a Petroleum $ Gas Engineering Student in one of the underdeveloped countries of the world,as a result,will be needing topics that won't give me too many constraints. I'm welcome to any suggestions though. Can anyone help me please?

Answer: The name is stupid, but try this: www.ScienceBuddies.org

Question: Can a chemical engineer work as a petroleum engineer? I'm almost done with a chemical engineering/chemistry combined degree, and was wondering if I can break into petroleum engineering with this degree, or if I would have to undertake additional training for that. Any answers welcome

Answer: Yes, but you would do well to have some geology training but that is not imperative. Some universities provide a dual degree in both disciplines.

Question: How To Get Employed As Petroleum Engineer? Well, I want to be a petroleum engineer, lot of my family are back home, when i say that, my friends joke around sometime saying that there will be no more oil left by the time i get to college and out and blah blah..... is that true, how many years left till petroleum engineers are deemed unneeded? ANYWAYS, my main question is most petroleum engineers have 10 years work experience, so how do you get a job quickly fresh out of college?

Answer: The use of petroleum will decline but there will be use of it for hundreds of years. They teach Petroleum engineering at West Virginia University and pretty well all of each year's graduating class has several job offers before graduation. Petroleum engineers are the most in demand of all engineers and this is a very good field to get into.

Question: Does anyone knows what is the status of employment on petroleum engineer technology in Canada? Im probably going to college for petroleum engineer technology but i was wondering how hard is to find a job and if is payed well? thanks

Answer: i no just the place where u can find that answer go to weatherbird.webs.com and watch our videos and become a member its all free also check out our webstore but as i was saying thats where u can find ur answer

Question: Average salary of a petroleum engineer in India? What are the maximum, average and minimum salary for a petroleum(chemical )engineer with a Master degree (from USA) in India? Who are the potential employers for Petroleum Engineers?

Answer: Starting 2.0 to 2.75 lakhs on an average 5 years + experiance 6 to 6.5 lakhs

Question: can a chemical engineer work offshore , go to refining platform to work like a petroleum engineer? some people said that a chemical engineer still can work like a petroleum engineer but when i read the curriculum design for petroleum course and chemical engineer course , it is a big different, i'm not sure after that can i study master of chemical engineer if i study petroleum engineer or vice versa?????

Answer: Yes, chemical engineers are just a broader version of petroleum engineers. Chemical engineering programs were born for oil and refining, and upstream, but has developed as chemical concepts have been applied to other fields of study. Do ChemE, you'll have more options.

Question: Will the BP oil spill ruin the outlook for future petroleum engineer jobs? Will the petroleum engineering industry be decreased drastically in the next 10 years because of the spill?

Answer: In the next 10 years I believe there will be an alternative fuel source. but in the immediate future i dont see why the outlook would be less just because of the spill if anything it would be more, because now they want to find people who can use what they recovered and turn it back into fuel that they can sell no clue just what i thought of when i read your question

Question: Would a B.S. mechanical engineer make the same salary as a petroleum engineer if they are in the oil industry? Generally wondering if the salary is the same for a mechanical engineering working in the petroleum industry versus a native petroleum engineer. Also, what if that mechanical engineer gains a masters in petroleum engineering...how would that compare to a B.S. petroleum engineering?

Answer: I'm not too sure on the first, but I would suspect that the petroleum engineer would make a little more. If you had a BS in MechE and a MS in PetE, then you would make more than someone with just a BS in PetE

Question: How much a fresh petroleum engineer with a masters degree from an average university from USA draws a salary ? How much a petroleum engg with masters degree from average universities from USA get salary approximately... Does it depend if he get offer from big corporations or small exploration companies... How much can one expect with masters in petroleum engg...

Answer: Anywhere from 80,000 - 110,000. It really doesn't matter whether it is a small exploration company or a major, most everyone falls in this range. A master's degree really doesn't make that much difference in pay, maybe a few thousand dollars per year.

Question: How much does a petroleum engineer earn? i am going to go to college next year and pursue engineering are there any engineers out there that can tell me how much does a petIroleum engineer earn right out of college with a 4 year degree? I heard it's like 50,000 and I mean that's what im making right now working? at my dad's company part time so I want to know if it really is worth it

Answer: If you're making 50,000 a year working part time, don't bother with college.

Question: What do you think of a Geologist/Petroleum Engineer future? What do you think of the future of both profession? I need opinion. I'm worried both wont have future because lack of oil supply and also the world is trying to replace petroleum with something else. Thank you so much for the feedback. No words can match my gratitude! I'm now going to do Geology!

Answer: I have been a geologist for 10 years, and have never regretted it. There will always be a job for you in pertoleum, however I don't think this should be your main concern. I would really seriously ask yourself whether or not this is the sort of lifestyle you want. You will work in some wonderful places and see some amazing things, but they will bein the middle of nowhere, where relationships are hard, even life is hard. It is not really dangerous, just harsh conditions, moving around a lot, so you lose trasck of friends as well. There will certainly be ups and downs in the employment availability side of things, but if you are a good scientist, you will always get a job.

Question: can a chemical engineer with master of petroleum work like a petroleum engineer? can a chemical engineer with master of petroleum work like a petroleum engineer?

Answer: Absolutely. A petroleum engineer is basically a chemical engineer with a specialty in petroleum processes, or in other words, a ChemE can do the same job a petroluem engineer can.

Question: what will it take for one to be a petroleum engineer.like the degree,courses,years etc? what will it take for one to be a petroleum engineer.like the degree,courses,years etc.is the course transferable after taking the basic courses at the community college.

Answer: Petroleum engineering is a top class degree subject and you will require top class results in Physics, Chemistry and Mathematics just to get on the course. Typically a degree course is 3 years but can be 4 years if it includes a year in industry usually after year 2. It is likely that you could transfer after the first year to Chemical or Mechanical engineering but I cant see why you would want to do this as the career prospects are excellent.

Question: Career Choice Petroleum Engineer or Geology? I currently live in Houston and plan on going back to school to work in the oil industry. I am stuck between petroleum engineering or geology. I believe i would enjoy both of them just as much. My question is this: which career has a better job outlook (salary, work environment, and job security)? I am leaning towards petroleum engineering since it will take me slightly less time to get a degree (since i would have to get a masters in geology), and am thinking about possibly chemical engineering with a minor in petroleum engineering. Thanks in advance for you input.

Answer: same.

Question: How do I become a Petroleum Engineer? The college I'm attending doesn't have a Petroleum Engineer option, so if I major in Chemical Engineering, can I become a Petroleum Engineer? If not, how can I become one? Thanks

Answer: Hi! Absolutely, I was offered a job in a refinery in Texas, and I majored in ChE, too. Petroleum engineers might explore the world with geologists exploring for oil and gas reservoirs, and they're divided into two main groups--drilling/completion and design/production. You would work with a geologist to determine what rock composition is present. You would also need to determine the most economic, cost-efficient way to increase recovery. You should have a knowledge of math, physics, chemistry and management. It's really a fascinating field. All of which you'll get with a degree in ChE. So many doors will open for you, so stay with it!

Question: What is the salary of a petroleum engineer and what are their hours if I have a family? and will I have time to hunt if I decided to become one?

Answer: The hours depend on the company. Family has no effect on hours.

Question: How many Math/ Science courses do i need to take to become a Petroleum Engineer? ,I'm considering becoming one, but not before i get a few questions answered. First: what is the highest math level that i need to take? Second: Which science courses will i be required to take?

Answer: Look at the web sites of the engineering schools you are considering. The requirements may not be the same at each school.

Question: whats the difference between a petroleum geologist and a petroleum engineer? Which are the pros and cons of each of them, and which one requires more travelling and has bigger salaries and more demand ?

Answer: The petroleum geologist finds the oil and gas and the petroleum engineer figures out the most effective way of recovering it. Both professions require some travel, but geologists always do more of that. Both are paid really well, but an engineering degree is always the better education to have.

Question: How many hours does a petroleum engineer works a week? I dont want to have a job that keeps me away from my family.

Answer: I know few engineers who work fewer than 45-50 hrs/week, and at times 70 and more. Some of that time might be at home, but it is not a banker's job or a school teacher's job. It is serious work.

Question: Is petroleum engineer a good choice for a career now a days? im really interested on this career but i dont know what is the employment rate for it in canada or even in this US. What you guys think?

Answer: My uncle is a petroleum engineer, and a couple of decades ago it was a really tough business to be in. Now he's making a ton of $$$$. It's probably a risky business to go into, but I see plenty of opportunity for the next few years. If you go into mechanical engineering, you couple easily move into the petroleum industry without restricting yourself.

Question: Do you think Petroleum Engineer will be a profitable career? Oil is decreasing do you think this career will still be in need?

Answer: Yes, those guys make reallly good money.

Question: Since every petroleum engineer says that everything that can be done has been done? Why are people blaming Obama for not handling the leak well?

Answer: Hate & Fear alive and well in American politics. The hate is so strong, I believe many would rather see our country fail versus give the other side any credit. Sad. It's getting a bit old, though.

Question: Who earns more money, a petroleum geologist or a petroleum engineer ? and which of those two has more demand on the job market ? Also, any other career ideas that pay like those that are not medical ?

Answer: Engineers by far make a lot more money than geologists, and a geologist may end up working for the engineer anyway. Electrical engineers are paid a lot more than most, along with mechanical and chemical engineers. I make over $105k a year but then again I've been working for a few years now. And the work is fun.

Question: If i do Bachelor in Chemistry can i become a Petroleum Engineer? after that do i have to do masters? what about if i do only engineering?

Answer: If your aim is to be a Petroleum Engineer, why not start with a B.S. in Petroleum Engineering? Why go round about starting with Chemistry? The Petroleum industry does hire Chemical Engineers in the refineries. They prefer Chemical Engineers rather than Chemists. Petroleum Engineerings looks at oil reservoir explorations, drilling, subsurface sciences. These are very different know-hows from other engineerings like Electrical, Civil, Mechanical, Chemical engineering. If you really want to be a Petroleum Engineer, I would advise you to go into Petroleum Engineering degrees.

Question: What classes should I take in high school to major in petroleum engineer in college?

Answer: Chemistry, math, physics. You could talk to your school counselor or research on the internet or talk to a college counselor.

Question: Is it possible to apply for a petroleum engineer job with a civil engineering degree?

Answer: of course u can , but the demand of Civil in the oil industry isnt that big , so u should either have a connection or getting lucky , as the rewards are amazing. They do need , civil engineers there , i met some colleagues who used to work on such facilities

Question: What are the pros and cons of becoming a petroleum engineer?

Answer: Pro: You'll make alot of money. Con: When we run out of oil, the party's over!

Question: Can I get a job as a petroleum engineer in the midwest somewhere.? I am very interested in this field but I do not want to live in Texas or Alaska, I like the midwest. Could someone with experience please let me know if this is a possibility and if so where the work would be. Thank you.

Answer: Regardless of the degree you get, you will have to go where the work is. I think you are short changing your self by saying you won't work anywhere but the midwest. You need to try some of the other areas of the country. You will be surprised how much you will end up enjoying it. Don't be sucked in by the stereotypically ideas you and many others have about a certain part of the US. I have many engineering friends who are from the midwest and now live in Texas. They could have chosen to go back to the Midwest but have found Texas to be a very good place to live. I am sure that is also true for others who have chosen Colorado or California or Alabama or other locations. I have personally lived all over the US and have found there are many areas where I would be happy to live.

Question: Should i become a petroleum engineer knowing that the world is trying to find new sources of energy?

Answer: 30 years ago when I graduated, the world was looking for new sources of energy. So far there is NOTHING new. In the event that something does come up, the infrastructure is so well established for oil that it will be "king" for 30-50 years, regardless. That doesn;t mean employment will be up and down. Petroleum Engineers have had a tough time finding or keeping a job for decades. It is more sure in the Middle East, and a few other locales. The US government (like the EU) willl do their best to make oil uneconomical. Regardless, petroleum is a wonderful raw material for chemical synthesis, and always will be, and it is still incredibly plentiful. There will be work forever.

Question: who makes more: a pharmacist or a petroleum engineer? and what is their salary? who makes more: a pharmacist or a petroleum engineer? and what is their salary? - which of these two is better. and I heard that the world's oil is going to run out soon !!! - so please answer my question :) thanks !!

Answer: 30 years ago everyone knew that the world would run out of oil in 20 to 50 years. We now all "know" that the world will run out of oil in 30 to 50 years. It is running out just as fast now as it ever has, but there is an enormous amount of oil yet to be discovered. so, don't worry about that part. Petroleum engineers (when they can find work in the US) earn $60-90,000 to start and after 20 years make up to $190,000. Pharmacists earn $70-100,000 to start, and less than $120,000 after 20 years. It takes 6 to 10 years to get a degree in pharma (it is very fast becoming a doctorate degree-only program), and 4 to 6 years to get a degree in Pet E. Obviously PetE pays a lot better, short and long term. They both tend to work lousy hours and places, unless you like remote places or hospitals.

Question: What does a Petroleum Engineer do? Hi, I'm currently in my freshman year at a very prestigious college. If I choose to major in Petroleum Engineering, what specific jobs will I be qualified for? Also, would I be qualified for jobs outside of the petroleum field? Also, how do you believe the coursework for a Petroleum Engineer compares to that of a Chemical Engineer? Is it easier or more demanding? Thanks

Answer: There are three sub-fields in petroleum engineering: 1.) Reservoir engineers work to optimize production of oil and gas via proper well placement, production levels, and enhanced oil recovery techniques. 2.) Drilling engineers manage the technical aspects of drilling both production and injection wells. 3.) Production engineers manage the interface between the reservoir and the well, including perforations, sand control, artificial lift, downhole flow control, and downhole monitoring equipment; they also select surface equipment that separates the produced fluids (oil, natural gas, and water). The coursework for Petr. Engr. is quite similar to chemical engineering except is has more Mechanical engineering theory behind it. It's going to depend on you whether it is easier or not. It will be a little less chemistry than ChE and will have more ME curriculum. With a degree in PetrE (from a "prestigious" university nonetheless), I'd say that you shouldn't have that big of an issue finding jobs that are tailored for ChE's or even ME's.

Question: My mother doesnt support me at all with my future career goal of Petroleum Engineer? She says it's stupid, that we will run out FAST (Hello! Hubbert curve! Asking people in the indusrty and them saying "not any time soon"), the world will change fast for the worst in a few years with global warming and all that crap. Nagging that I will be hurting the world She has become a hippy environmentalist, she threw away our microwave because she read it was unhealthy....

Answer: You do know that global warming is not real right? Just as many scientists oppose it as support it, and it seems that it is leaning towards oppose at this moment. That being said we still do need to find an alternative source of energy for when the oil does run out, but I believe that you should do what YOU want not what mommy says. Besides she threw out your microwave dude... That's effed up

Question: what do i need to become a Petroleum Engineer? how many years of school, what would be the best school in california, is it a good job to get into

Answer: I'd be scared to major in Petroleum Engineering. What happens when they find a replacement for oil? You're SOL, just like buggy whip manufacturers. If I were going to pursue a PHD, I'd much rather go for accounting. You'll make just as much money a PE, possibly more, and all you need to know is adding, subtracting, multiplying, and dividing.

Question: Tasks of electrical engineer in petroleum marine services companies? What are the Tasks of electrical engineer (recently graduated) in petroleum marine services companies in the sea sites

Answer: Im not an electrician, but I do work offshore. Basically you will be a sparky in a zone 1 rated work setting. Zone 1 is the area immediately around a wellhead, storage vessel or refinery, where all electrical gear must be intrinsically safe so no sources of ignition can occur. Oil platforms, drill rigs, FPSO's tankers etc will all be zone 1 for this purpose. the rules for work in these areas are quite strict, as the stakes are quite high.

Question: What subjects should i take in high school if i want to be a Petroleum Engineer?

Answer: you better start loving math and science.... when i was in high school 2 years ago i was bad at math but know i like it :)

Question: Petroleum vs Computer engineer? I am going to college and I wanted to know which is better. I know both careers favor math and science. I already chose computer engineer as my major but might switch over to petroleum because I hear that the money is great. Should I? Is being a petroleum engineer harder than a computer engineer? I know a lot about computer hardware already (I can build my own computers). I just wanted to know if it would be worth it. Oh yeah, and I actually do enjoy math and science in case youre wondering.

Answer: I can't speak on behalf of the petroleum engineering because I know nothing of it except the fact that my brother is starting to study for it this coming August. Anyway, as far as computer engineering goes, just because you know about building your own computer doesn't mean you know ALOT about computer engineering. CPE consists of hardware and firmware stuff, which means you'll study alot about how to program and how electrical components and circuits work. It's one of those where either you like it or you don't. It seems that you're interested in this kind of area to begin with so it's good. As for money wise, generally I can tell you that entry level engineers start quite high compare to other majors. I know entry level EE and CPE last year (and maybe this year) make approximately between $55K to $65K to start with ; I know this because I was a fresh EE graduate last year as well and just recently got hired. Hope I gave you a bit something to think about, good luck buddy

Question: I wanted to be a civil engineer but I'm majoring in Petroleum engineering at New Mexico tech.? It is true that I will make a lot of money when I graduate. I’m doubtful cuz my friend liked sociology but got a bachelor in nursing. He graduated six month ago and can’t find a job.

Answer: If you got the "experience" under your belt then yes. Otherwise, no. And you too, will be over-qualified for non-degree positions for no apparent reason other than the fact that you have a worthless piece of paper called a degree. However, engineering is in high demand so you may do better than those graduates with a liberal arts based studies.

Question: where in the world could a petroleum engineer earn the highest salary?

Answer: it may be in saudi

Question: How To Be A pEtroleum Engineer? i am going to the sophmore year in high school and i know you need math, physics, chemistry, computer science, economics, and natural science, but i don't se any class called natural science in my school?

Answer: Natural science is probably just another name for biology. You should have it already. If not, ask your department office.
