This is a terrific book. It makes me feel that I shouldn t bother to attend my math class in school. The book explains concepts clearly. You don t even need a mentor. You can manage the book all by yourself, for the book itself is your teacher, your mentor. There is an abundance of exercises for you to practise. They never run out of it. It makes you feel that math is fun. It is the simply the best way to learn math. The best part of the book is the review after every chapter. I can learn back whatever I ve missed. I m an 8th grader only, but I can still manage the 2nd year of high school algebra. The book has helped a lot. The book is perfect for talented 8th graders.
