The Best!!!!!
Format: Paperback
These practice tests are excellent. I feels so lucky to have found this prep book for my daughter right before the big test in May. The explanations for the main idea questions, fill-in-the-blank parts, and rewriting sentences were super useful and helped my daughter get a score over 700. Can't wait for the next book to come out!!
