In summary: Exactly. Deriving from first principles would be a waste of time and if...I would recommend you retake the GRE with this strategy in mind. He said memorize and understand. On these tests you do not have time to re-derive equations from scratch. You have to not only know all the equations, but understand how to use them to succeed.I took the GRE with a similar approach and have done very well. The point of exams is to test and reinforce your understanding skills - not memorizing skills.

Physics GRE is more important. You may have had test jitters.

But you also mention that there wasn't enough time. Which means you might have been answering too many questions. Sometimes it is quicker to eliminate the wrong answers than to calculate the right answer. In a sense, you only have to do enough calculation to eliminate all the other answers. But this is also dangerous because you are less likely to notice a mistake if you aren't doing the whole calculation. You won't get numbers that don't look right.

So in that sense, it is a combination of conceptual understanding and finding the weakness in each question. Is the weakness the fact that most of the given answers are easily shown to be incorrect? Is the weakness that a formula I know will lead directly to the answer? Or is that a trick?

Another thing to consider is that practice tests are never as difficult as the real test.

Try that for the physics gre. These are timed exams which means you will need to memorize and understand.

I also find it more efficient to learn the concept otherwise blindly plugging numbers into an equation that you don't understand is a recipe for failure

Neither are mutually exclusive.

Exactly. Deriving from first principles would be a waste of time and if we were referring to the physics GRE it would be impossible ( you are going to make qft calculations and prove conservation of lepton numbers)

first, when are you applying to grad school? if you have time you should try tutoring. for me, i believe tutoring for over three years steeled my gre score (i can finish with about 10 minutes to spare, getting every question). doing math every day and teaching it solidifies understanding and makes you impeccable with mental math (as previously mentioned, youre probably making dumb errors)

second, as previously stated, take the specific gre, as most universities require you take both! you may do better??

lastly, NO, youre not out of the game. gre is a graduate school requirement, and perhaps the department only requires you meet the minimum? but if youve done well in upperdivision RELEVANT courses youre probably fine, depending on where you want to go.

hope this helps

My first time around the general exam I got 150 on the quant. Second time -a year later- I actually did worse, 149, but actually improved substantially on the verbal (studying vocabulary paid off). Got the exact same score on the analytical writing on both exams, despite having radically changed my approach, I think grading in this section is pretty arbitrary.

If it is of any consolation, I shared the (subject gre) testing room with an Oxford math major who said he did even worse than I did on the quant section. You can probably do definite integration of most transcendental functions in your head, I know I can do it faster than an "ugly" numerical long division to anything beyond 2 significant digits without going for "spherical cow" approximations.

I don't know what this means, probably not a whole lot if you've got all the coursework done. If you've made it through the bulk of classical and modern physics coursework, it certainly doesn't mean we're unable to do geometry, basic stats, combinatorics and word problems, but I happen to be terribly slow on the GRE and having to read problems off of a screen instead of paper is an added annoyance for me, as I usually like to make a few scribbles immediately below a word problem as I read it or immediately start drawing on geometric figures. I am very prone to copying down a number wrong from the screen, maybe you are too.

The only thing I can say is: speed up and sharpen up your mental arithmetic and read problems carefully. Also try hard to keep your hands off the pencil. The GRE only tests your ability to take the GRE (with the time constraint being the main hinderance).

no prob. a quick point, you say you had to "Christmas tree" and by that i assume you refer to guessing abcdedcba in a zigzag way? from a mathematical perspective, this is ill-advised. when guessing in the fashion you have, you limit yourself to 20% per question, and likely you will miss every question. however, if you guess, say, B on each remaining question, you will notice the odds of at least one question being B increase, and perhaps you walk away with a correct answer.Hercuflea said:I ran out of time in the first section which determines more of your score, with 1 minute left and 5 questions to go I had to christmas tree and I wasn't even able to click on the last one.

hope this helps

Thanks for the advice. When I say "Christmas Tree" I mean that I just randomly picked answers in no particular pattern because I had one minute left and about 6 questions to go. I actually have already done undergraduate research with the advisor I am wanting for my Ph.D. at my top school choice. However, I am worried that they will change their mind about me once they realize I am a mathematics major who scored a 158 on the GRE math :(... I may take it again, but I'm bad at time-restricted tests and worried I'll screw up again.

A good score for the GRE quant section varies depending on the program you are applying to. Generally, a score of 158 is considered above average and can be competitive for many graduate programs.

It ultimately depends on the program you are applying to and their specific requirements. Some programs may have a higher minimum score for the quant section, in which case it may be beneficial to retake the test. However, if your overall score is strong and meets the program's requirements, you may not need to retake the GRE.

While the GRE score is an important factor in the admissions process, it is not the only factor. Admissions committees also consider your undergraduate GPA, letters of recommendation, personal statement, and other qualifications. A 158 in quant may not have a significant impact on your overall application if your other qualifications are strong.

There are many ways to improve your score in the GRE quant section, such as practicing with official GRE materials, taking a prep course, and studying with a tutor. It is also important to familiarize yourself with the format and types of questions on the GRE and to develop a study plan that works best for you.

No, a low score in the quant section does not necessarily reflect your abilities as a scientist. The GRE quant section tests mathematical and analytical skills that may not necessarily be directly related to your field of study. It is important to remember that the GRE is just one aspect of your graduate school application and does not define your potential as a scientist.
