As far as practicing, there are still books of "Real GRE's" (put out by College Board) out there, and they are invaluable for experience with real questions, and the levels of math and verbal skills you'll need to dredge up. Find 'em, and I'll tell you the best way to use them.

BTW, for most grad students, the verbal sections are considerably easier than they were when you took the SAT's, because you've presumably been using the language, and the math is considerably harder if you haven't used it.

I have to put my $.02 about test prep, since I have no interest in the field whatsoever, but plenty of experience:

- it IS a gigantic racket, even more so for SAT than for GRE and other grad exams, and it is hard to tell fact from fiction.

- many people would do just fine without it

- many people do MUCH better with it, having worked with someone who is familiar with every in and out of the test to focus their preparation, and hone the skills they might be rusty on. I've found that for high school students, that is in verbal prep and vocabulary skills; in grad students, it is in refreshing math skills.

The value of professional test prep varies depending on what kind of a student and test-taker you are/were.
