GRE Physics (REA)
This
test preparation book includes four full-length exams with detailed
explanations modeled after the actual GRE in Physics. Knowledge of
mechanics, electromagnetism, atomic physics, physicoptics and wave
phenomena, quantum mechanics, special relativity, thermodynamics and
statistical mechanics, laboratory methods, and advanced topics tested.
Includes a general physics review of all topics tested on the exam. For
physics students bound for graduate school.Format: djvu

Fairly straightforward: KNOW THE WORDS.
Suppose you get hit with "AVER".
Now
what? If you're one of the few people that knows the definition of
AVER, great, find the word that means the opposite and move on. If you
don't know what it means, well, there's not much more that you can do
but decide which one of the first five letters of the alphabet is
momentarily your favorite.
So, start memorizing some words.
Flashcards are the easiest way to learn words.
How to improve your GRE math score
1. Master the Fundamentals
During the tutoring sessions, we go over and master all three facets of the test. First, we assess your basic math ability and decide whether you should spend some time strengthening your computational skills before going to the actual GRE. It's important to understand that you won't get a good score if you don't know the basics of arithmetic, number properties, algebra, and geometry, and that it's counterproductive to try the more difficult questions that are in the official guides without first getting a strong foundation.
To put it in basketball terms, if you're scoring below 540 and you want to jump straight into actual GRE questions, that's like trying to shoot 3-pointers without knowing how make a layup. Most likely, you need to do at least a little drill work so that you can do the arithmetic on the test more quickly. Also, at this stage, force yourself to show all your work. Writing all your work down when you do a math problem greatly reduces the amount of errors you make, and it also SPEEDS UP your math solving ability.
2. Develop your ability to solve the problems through creative thinking, reasoning, and looking for patterns.
Arithmetic ability is just a foundation, and it alone will not get you a good score. As you do the more difficult problems, you'll see that many of them are like the second question above. What may at first seem like a problem that requires tons of computation turns out to be fairly straightforward and less time consuming once you spot a pattern or use reasoning. Tutoring is very helpful in this regard. Together with your tutor you can go over all the different types of problems and learn the most efficient ways to do those problems, so that ultimately you can do every problem on the test in under two minutes.
3. Learn to manage your time more efficiently.
Essentially, , you need to learn how to recognize questions that will suck away at your time. Then you need to discipline yourself to skip those questions with some educated guesses. It is possible to miss as many as 9 or 10 questions on the math section, and to still score in the high 700s. This means that you don't actually have to do 28 questions, but 18, provided you get those 18 right. The bottom line is, guess on the questions you're likely to get wrong, and spend more time on the ones you know that you can get right.
Also, keep in mind that the GRE is not a math test, it is a test with some math in it. For a large number of questions that seem to require a ton of computation, often you can do the question much more quickly by checking the answer choices or substituting simpler numbers in. You should learn to recognize those opportunities, and use them to your advantage. In general, whenever a question seems to require excessive computation, i.e., a calculator, there's an easier and faster way.

Why is the math on the GRE so tough?
Well, for some of you, the math on the test will be tough because tenth grade was a long, long time ago.
However, the quantitative part of the GRE doesn't just test whether or not you remember all the pre-algebra you learned as a teenager. For example the question on the previous page really tests your ability to reason through a problem and to spot a pattern. So, the GRE measures not only how well you can do basic math, but also how well you can think critically and creatively about problems. That's what makes the questions so tough.
Furthermore, on the test you will only have, on average, two minutes to answer each question, which makes the whole thing even more difficult. In other words, you are also being tested on your ability to focus and to perform efficiently under pressure. If you keep in mind the three things you will be tested on (basic math skills, reasoning ability, focus/working under pressure), then it will be easier to know what to study and how.
