"Just wanted to thank you very much for your help so far! I used to score in the mid-high 400s, now I consistently score around high 600s - low 700. Hopefully by June i will be scoring in the high 700s. Well anyways, this was just to thank you and show how your book (The 32 Most Effective SAT Math Strategies) helped me immensely."
"The Red Book [320 ACT Math Problems] helped my son raise his ACT score in math from a 21 to a 26. He is a good math student but fails to Deliver on a lot of standardized tests . The concepts were well explained . Like a lot of reviewers said the concepts are categorize in different areas from easy to hard. We have tried other ACT books and this one seems like one of the better ones out there. What people don't realize is that there are a lot of pre-algebra concepts that their son/daughter may have learned before high school that are on the ACT . This book does a good job of going those concepts and some of the test question replicate what you see on the actual ACT test."
"I'm a big fan of this author's writing and teaching style (I have his 320 SAT Problems books and ACT book). The organization of his books allows you to go right to the problems you need to focus on without wasting valuable time. There's something I really like about this book in particular [320 AP Calculus AB Problems]. After each question the author gives a quick straightforward solution, so if you understand the answer you can move right to the next question. But if you don't get it right away, the solution is followed by an extensive set of notes which gives a complete review of all the concepts used in the solution, walks you through the solution step by step, and gives additional methods for solving the problem."
"Best purchase I ever made [555 Geometry Problems for High School Students]. We are very very pleased with this book. Thank you for the solutions , not just answer, solutions and explanations and drawings. This is a real help for high school students. The content is very dense, and it takes some study itself to gain facility in using it well. This book is clear, concise and extremely well written. Recommend to anyone who wants easy tools."
