<p>I have taken three CB practice tests and my math scores are 630, 640, and 680. Is Dr. John Chung's SAT Math right for me? I usually miss the last 2 questions at the end of each math section and I want to score at least mid 700 for the actual test.</p>
<p>I have the book, I recommend you not to buy it. It’s a huge book with many errors in it.</p>
