Thanks, Kaplan!I bought the book with plenty of time to spare, but didn't wind up seriously studying until within a week of the test. The book got me started early on with the math concepts I needed to review. Then, during the crunch, the CD-ROM was priceless practice with the frantic, clock-ticking real test situation.
