I was blown away by these scores, as it beat anything I got on any practice tests, PowerPrep or Barrons, by 90 or more. I started preparing about a month ago (I'm a true procrastinator!), going through practice section and practice tests over and over again until I gained familiarity with the question types. I then just studied a list of 4,000 words from a seemingly lesser known GRE book by NOVA. Their word list was better than others I had seen from the more major test books.
The math section was considerably easier than any of the practice tests I had taken, the part with graphs was kinder, and the bar graphs didn't require any estimation: all the bars rested on the lines. I always was finishing the practice tests with less than 2 minutes left, and so it was absolutely essential to be familiar with the kind of shortcuts you can use in the calculations. There were a few times I just decided to go ahead and brute force it, but the less you do that, the better. The geometry questions were just straightforward applications of the basic geometry rules listed in all the books, and exemplified in all the practice tests I saw.
As for the verbal section, I had 2, and can only guess I got lucky in which one was counted for the score. While taking the test, I thought I was not doing very well at all, as I felt unsure about a high percentage of the questions, especially the analogies and antonyms. Here the words I had studied didn't seem to be as important as the actual relationships and strategies for the question types. A little reasoning can go a long way on these. But then again, I read regularly and that helps a lot, especially in the dense RCs.
Anyways, I had read posts on this forum in advance of taking the test, and just wanted to let people know that with some hard work (well..studying that much is way more than I'm used to!), a cool head, and some reasoning ability, you can definitely get a better score than you expect! :D
