I used Cliffnotes Standardized Test Math Review, but it didn't have test examples, just lots of practice problems with concepts and methods. It was helpful in reviewing tricks and tips to save some time on problems. I also used Barron's and Princeton Review books and signed up for merriam Webster word of the day emails, which are free. Flashcards are helpful for some people but I didn't find it that helpful so I tried reading articles from the Atlantic, Economist, etc, just to be more familiar with types of readings that may be on the test.
