<p>I found the Princeton Review Tests to be pretty close to the real exam, especially the free-response sections. I didn’t look at any other review books, although I did read over the Barron’s flashcards. I went through 100 cards a day, and after the end of the 5 days I felt like I was completely prepared. I think that the flashcards helped more than the Princeton Review book, although the tests were helpful.</p>
