Although this book was created by The College Board, they do not give you the important information that's needed to be successful on the test. I recommend booklets from Kaplan, Barron's, or The Princeton Review. Or any other brands.I bought this book in hope that I will get good information, but it's too packed up with all of thte SAT Subject tests with brief info for each and practice tests that it hardly focuses on the subjects you will be taking on the exam. The SAT Reasoning booklet is very comprehensive and worth buying, but this book is NOT.I still have this book with me, but I don't recommend it to others. It's a good thing I bought it for a cheap price, but I think other reference booklets will be more helpful.
