Princeton Review is good. There is also – believe it or not – a “GRE Test for Dummies” which I used in 2003 when I had to retake the GREs. I presume they also have an “SAT for Dummies” which is equally as good.
There are two parts to taking these tests. One is the subject matter. Schaum’s Outlines has good books for math. I’m not sure about verbal because I didn’t need to do too much for that.
The second, and most important part, is how the questions are set up and scored. This has nothing to do with the content, it’s just what the test-takers want. The Dummies books are good for that, also Princeton and anything else you can find. Yid.Period is right. You can know the subject inside out and still flunk the test, especially the quantitative.
The most important thing is just to take practice tests. As many as possible, from books and especially from the SAT website. Take them, score them, and analyze why your answers were wrong (or right :-). Practice the writing part and try to find someone knowledgeable to look at your papers.
And expect to get stage fright. I assume you’re going to be tested on computer, so do as many computerized versions as you can (e.g. on the SAT website).
I wouldn’t wait until June, though. Do a little bit every week – say one or two practice tests a weekend. Spacing the learning out makes it stick longer – and be less likely to desert you in the critical moment.
Good luck!
