Good structure and pacing of the lessons. I would have appreciated a progression in difficulty of practice questions for each lesson but this was focused on repetition, making it better for first-time learning than review. I was just looking for a refresher so I wound up doing a smattering of problems from throughout each set in the hopes that that would net some variety. Found a couple errors in the answer guide in back, although usually the answer provided was one of the numbers reached in the course of determining the answer to the original question.
