I severely dislike this book. Rather than reinforcing the fundamentals that will be tested, it goes into mathematics using methods and formulas it expects you to memorize. It's basically the "asian" approach to math, to put it in the simplest and most politically incorrect terms. If you want a more logic based approach to the material, with practice tests that actually reflect what will be tested, I recommend Princeton Review or Barrons. I got Chung's based on high reviews and the ample # of practice tests, but it was a mistake. The practice tests are too difficult, making you unable to focus on the timing, speed, and fundamentals necessary to get through all the material. Instead, you get bogged down by ridiculously tedious and advanced problems. Additionally, the language used in the problems is nothing like what you would see on the actual test, and for good reason! To add another politically insensitive comment, it reads like a chinese wrote it... I'm sure Dr. Chung is a very brilliant and talented man, but the flow of language in the book is very unnatural, and can be quite unsettling to read, even when grammatically correct.
Here are the first two problems of the first practice test, talk about getting off to a rocky start. Or, maybe I'm just a moron.
1) If a(x+2)+b(x-1) = 3 for all x, then a =
A) -1 B) 0 C) 1 D) 2 E) 3
2) If a+b=2 and ab=-1, then a^2 + b^2 =
A) 4 B) 5 C) 6 D) 8 E) 10
