It is not helpful at all

Each chapter has less than a page of explanation about the topic. Seen as the test is very unique about the way it asks some concepts, the small explanations don't help at all. Also, it spends little time trying to just explain how to do it in the calculator but I found those explanations not helpful at all for what it asks you to do in the practice problems. Really disappointing considering the other SAT books by this brand. Do not recommend it for anyone who does not have a good understanding of math and the test already.
