Choosing and using and AP review book is a GREAT idea. It would be ideal to have one from the beginning of the year to help with concepts unit to unit, but at the very least all students should have a review book prior to the exam. Sadly, because the AP Physics 1 curriculum is still pretty new, a clear leader in the review book category has yet to emerge. So really, you should choose a book based most on how you like to review. Some of the available books excel because they have an abundance of practice questions. Others excel because they are concise and really emphasize the major content that you need to understand. The best would be a combination of both of those things, but it doesn't seem like that is available yet. Whatever route you choose, having any review book is better than not having a review.
