I used Baron's for the SAT Math Subject Test and it was great. However, for the reading Baron's was terrible. My main issue with this book is that the questions in the practice tests ARE NOT similar to the questions you will actually see on the test. Most books especially Collegeboard's have acurate questions. However, this book had styles of reading comprehension questions that I had not seen in a dozen practice tests. Baron's had a lot of "pretty general" questions that would ask about details from a group of paragraphs. I had never seen this sort of question. Baron's asks a lot of these. Other practice tests that I have seen had a lot of questions asking about main ideas, tone of the passage, comparing passages, and specific detail questions (citing specific lines). Baron's had a few of these questions types, but definitely not as many as on other tests. My point is that Baron's may make you a better critical reader through these exercises, BUT it will not prepare you well for the types of questions you will see on the SAT reading test. There were also a lot of typos in the book. Lastly, the sentence completion questions were alright and the vocabulary lists were good. However, this does not make up for the inadequate reading passage questions.
