content: This book was filled with an unbelievable number of mistakes. On every test, it always gives wrong line numbers and misspells many, many, many words. Often (a few times a page) it forgets to leave spaces between words. There are no tables to convert your sample tests into SAT scores. And to top it off, the answer guide is often wrong. This was the worst $10 that I have ever spent. Save yourself money, don't buy this horrible book!
