Query: great review of algebra

I havent had algebra in over 30 years and am getting certified to teach high school math. This book takes you through the review in a very thoughtful sequence. I did all the exercises in this book in just one week, completely refreshing my knowledge. HOWEVER, I was very frustrated by numerous mistakes in the solution sets. I wasted much time trying to figure out how they could have gotten their answer only to discover they were wrong (typically a typo). This book would not be good for people who are learning algebra for the first time, or did not really understand it the first time around. But it is VERY GOOD for refreshing knowledge buried deep inside your brain.
