This may be a double post, because I can't find my first posting. I am thinking about buying Aristotle Circle's TJ Test Prep Book for $200. Has anyone else bought this book? Is it worth the big price tag? I bought the SSAT books on Amazon but they are missing some of the subtests. I want to give my son the best chance. His teachers say he is likely to get in, but I know it is super competitive and a few extra correct questions could make all of the difference.
