Materials I used:
I bought a lot of prep material, because I wanted to be as prepared as possible and more importantly, because I wanted access to practice tests. Here's how useful I found them:
- Barron's GRE Book: Very useful for both verbal and quantitative. It had the 3500 word list for verbal, and tons of detailed math concepts and questions for quantitative (it's really helpful if you stopped doing math since high school and need to review some basic concepts). Not that great for analytical writing and only has pen-and-paper practice tests. I highly recommend this one.
- Kaplan's GRE Book: I like Kaplan. It had a lot of questions. The practice tests were online and computer-adaptive. It also had a great analytical writing section. It's decent, but I didn't find it to be necessary.
- Princeton Review: I found this to be the most useless. I only bought it so I could use the online tests. The material this book covers is very superficial and the book's style treats you like a five-year-old. If you're tight for time/money, don't buy this.
- POWERPREP software from ETS: Everyone writing the GRE should download this software (it's free on the GRE website). It has some very nice practice sets, and great practice tests. The tests you do here really correlate with your actual scores.
- Make sure you do practice tests, especially the computer adaptive ones. They give you a good feel for the real GRE itself. This especially goes for the POWERPREP ones, because to be honest, the GRE software is pretty rudimentary, so for those very into technologically advanced things, its simplicity may need some adjustment.
Verbal:
- The best way to ensure a good score on verbal is to study vocabulary. As much as you can. I recommend the Barron's 3500 word list. I made stashes of cue cards on words I didn't know or was uncertain of from this list. I personally felt that it really improved my vocabulary in general, helped with my analytical writing, and definitely made my verbal score go up.
- If you don't have time for studying all these words, try to study as much as you can, and focus on words that the GRE likes to use (these are usually highlighted in the books).
- Read newspapers, books, do crosswords, watch TV - these will all help you with vocabulary. These media also use the words in proper context, so you'll remember better. Personally, I really liked seeing GRE words used on shows - it really gives these words perspective.
- There are root lists and strategies that the books teach you, but I personally didn't use them as much.
- Work on things you aren't as good at.
- Pace yourself. 30 minutes is more than enough to do all the verbal questions. Don't rush, especially the first 10, 15 or so, since these count more towards your score. If anything, spend more time on these.
Quantitative:
- This is just math until grade 11, plus some random standard deviation, permutation, and combination thrown in. Make sure you remember the basic math concepts - for example, 0 is neither positive nor negative; 1 is NOT a prime.
- GRE math is pretty easy if you know what they ask for and if you avoid the tricks they pull. For instance, on the GRE, unless a triangle has the 90 degree square in it, don't assume it's a right angle triangle even though it looks like one.
- Sometimes it is better to use the strategies the books teach you, even if it looks incredibly ridiculous and "not mathematically advanced." I used to ignore the technique of substuting numbers and would derive equations, because well, I was being a mathematics elitist (and because my Asian-ness made me feel bad about doing things non-mathematically :P). Don't do that! Substituting numbers (or whatever technique) may be faster.
- Sometimes though, deriving things mathematically is faster. So just judge each question as you go. This is where practicing comes in handy.
- Again, pace yourself! Make sure to get the first 10, 15 or so questions.
Analytical Writing:
- I didn't really practice much for this section. I wrote about 5 essays for each category when I had time, usually when I thought the topic was interesting. It was really so I could get used to the pacing of the essays rather than the content. Seriously, if you've been to university and have taken essay courses, you know how to write. One of the essays is arguing a point, the other is criticizing a paragraph.
- One thing that I liked was typing my notes/thoughts directly onto the computer, instead of writing them down on paper (like some books will tell you to). It's just faster to type, and you can just rephrase your notes into the essay. This especially helps if you somehow run out of time - having some notes is better than nothing.
- For the one where you analyze a paragraph, just be as critical as you can. Find all the bad sampling, specious reasoning, instances stating correlation as causation, etc. Then argue those points.
Other:
- Don't over study. It will just overwhelm you. When you feel like you're ready and if you're getting some decent scores on the practice tests (emphasis on the tests provided by POWERPREP), just relax.
- The day before the GRE, don't study or take a practice test. Relax.
- On the day, remember to pace yourself for each section. Oh yah, the GRE people may give you experimental sections during your test, and these may or may not be identified. So budget that into your time for the test. I was lucky and was done in about 3 hours, but it may take longer than that.
