This review book is absolutely terrible. It's nothing more than a quick cash grab by Barron's. It says on the cover that it reflects the new 2018-19 curriculum, but this could not be more untrue. The book retains much of the material from previous years which is completely unnecessary. The layout of the book is also incredibly confusing: it is filled with too many tangential connections to modern events that really aren't needed. Focus more on court cases and key terms! Lessons, practice tests, and answer keys are also filled with blatant typos and errors.
Whatever you do, don't buy this book. Use CollegeBoard's practice test and review with your teacher.
