# GRE Math Subject Test

I am studying for GRE Math. I am looking for specific tips. What types of questions usually come up? Does anyone know any tricks (e.g. integration tricks) that might be helpful? Which theorems are absolutely essential? Apparently, most of the test is calculus and probability theory. What types of calculus and probability questions come up? Overall, how to score high on the GRE Math? Please be specific.

Edit: Please do not state the obvious. I know I need to study and take the practice tests. I am looking for specific tips and tricks that might help answer some types of questions faster.

A specific tip: take as many practice tests as you can get your hands on. Pay attention to the time. If you don't work efficiently you will not answer all the questions. I've known some good students who went into the exam without taking practice tests and they did poorly because they weren't ready to work as quickly as they needed to answer all the questions. – KCd Oct 20 '12 at 23:55
So, did you downvote our answers? I know, for example, that you downvote a lot more than upvote, and that you have 2 downvotes today, which as far as this site is concerned, just started 40 minutes ago. – Graphth Oct 21 '12 at 0:39
@Graphth Just to let you know -- voting is a feature of StackExchange. So what is your concern? – glebovg Oct 21 '12 at 0:49
I voted to close this question because it overly broad, which falls under "not a real question". Essentially, his question is, "What are tricks in any subject of undergraduate mathematics that could possibly make some GRE problem simpler?" It's too broad to even answer. – Graphth Oct 21 '12 at 0:54

The Math Subject GRE is 50% Calc 1, 2, 3, and Differential Equations. High school algebra and linear algebra are another 15-20% probably. If you do well on just those questions, you will be in the 70th or 80th percentile. Note, this is compared to students wanting to study math at graduate school, so this is very good. So, concentrate on those. But, also learn as much other stuff as you can.

Here is a link to a previous test, including the breakdown of subjects.

Note 25% is "Additional Topics". You'd need to learn several semester courses worth of material to get this stuff. Don't worry about that too much unless you are already pretty good at it. Notice that probability is a subcategory of a subcategory in this category. So, I think you are not quite right on how much probability is on the exam. The point here is concentrate on your strengths. Learning an entire new subject may get you 1 extra question. You're much better off mastering Calc 1-3, Differential Equations, and Linear Algebra. If you are already good at other subjects, then good, practice problems on those too but your time on those should be less.

When I studied for it, I used a test prep guide and I studied a lot of calculus from my calculus text book, for the most part.

I never memorized such tables, but the two examples you give can easily be rederived from scratch. (1) y = arcsin(x) ==> sin(y) = x ==> cos(y)dy/dx = 1 ==> dy/dx = 1/cos(y). Then use cos(y) = cos(arcsin x) = sqrt(1-x^2). To get that last one you need to draw a little right triangle diagram with angle y and sides x and sqrt(1-x^2). (2) cot = cos/sin = sin'/sin, so an antiderivative is log|sin| + C, more or less. – KCd Oct 21 '12 at 0:05
@glebovg I want to reiterate what I said earlier in the comments, and what Neal said in his answer, you have to study. It will be hard work if you want to do well. If you can't work hard, there's no reason to go to grad school. And, in grad school, you will want to know all this basic calculus stuff when you're teaching. So, you can figure out a few tricks here and there to make it easier to memorize. But, just memorize them. Take the time, put in the work, do it. There are no magic tricks to eliminate hard work. – Graphth Oct 21 '12 at 0:08
@glebovg Just go to the chat room and ask this question there if you have a bunch of follow up questions. The comments are not meant for this. Math isn't about memorizing formulas, but doing a bunch of problems as quickly as possible is going to work out faster the more you have memorized, and try to do math without memorizing formulas. I got 81% on this test and I'm an average grad student at an average school. I know what I'm talking about. You said you want to do well on the test, memorize the stuff. It's not like it's hard. You can memorize all integral formulas in an hour. – Graphth Oct 21 '12 at 0:13
@glebovg: math is indeed not about memorizing formulas, but it's not about filling in answers to a multiple-choice test either. The GRE math subject test is largely not a test about math, then. Whether you like it or not, you ought to memorize a few basic derivatives and integrals, and practice computing double integrals and finding eigenvectors from the exercises in a calculus and linear algebra book. As I said elsewhere, sitting down and taking past practice tests (real ones, released by ETS) will give the best sense of what the actual test is like. – KCd Oct 21 '12 at 1:38

Consensus from people I know is that the current tests are generally a bit harder than the practice tests which are available. If you want to score about the 85th percentile on test day, you should be able to finish a practice test to about the 90th percentile in a little over 2 hours having never seen that particular exam before.

Another thing is that it helps to have a familiarity with the sort of calculus questions that are asked on the test, and a good strategy can be the following: grade for advanced calculus or beginning real analysis classes at your undergraduate institution. I found that having been a grader for my university's honors calculus class and a first quarter real analysis course helped because I had kept the knowledge in my head and I could quickly go through and do these sorts of problems. Other friends of mine who took the test who had graded calculus and analysis before reported similar statements.

Finally, it helps to keep in mind that doing well on this test does not correlate strongly with going to good graduate programs. Most reasonable places look at the math subject GRE and expect you to not fail it- it is not so important except as a basic hurdle to get over. What I've heard from admissions committees is that most important things are good letters of recommendation from professors.

I agree about the letters. – glebovg Oct 21 '12 at 0:57
@glebovg: While letters are the most important thing, some schools (including good ones) make a first cut of the applications whose subject test score is below a certain level (schools generally don't release that information, so don't ask for it here, but it's probably safe to say if you are in the 90+ percentile you'll be fine at most top places). You won't get into any math grad program in the US by excelling at the math subject test, but you could easily cut yourself out of contention if you do badly. Also, keep in mind that schools in Canada and Europe don't require this test at all. – KCd Oct 21 '12 at 1:31
What would you say is the bar for "failing" the MATH GRE? – pm021 Oct 23 '15 at 1:54

Be sure to study, especially if you are several years past the calculus sequence. This examination is not like easier examinations, where you can get a reasonably high score with little effort. You can't cram for it either - this is like a qualifying exam, where you need to put in consistent effort over several months. (As a bonus, the extra study will also help in your graduate classes when it is assumed knowledge.)

As far as tricks, I don't recall any that aren't standard. What I remember is a straightforward examination that touches on most everything in an undergraduate math curriculum. It didn't seem to be an exam that requires cleverness, just reasonable thorough ability with undergraduate mathematics.

@Neal The downvoter is glebovg, who changed his question to add in smugly "Do not state the obvious" and then downvoted both of our answers because we don't give him magical formulas to make this test magically easy. I'm never answering a question for him again, not that I'm so full of myself to think that will really hurt him. But, hopefully others will do the same and that might. Note 80% of his votes are downvotes. – Graphth Oct 21 '12 at 0:51
