<p>The AP exam is very manageable if you use Barron’s and Crash Course. 5 steps is an excellent book as well, and the end of chapter “rapid reviews” helped me ace class tests this past year. I’m sure you could substitute it in for Barron’s if you like its style better. Good luck! As long as you get through the material and understand majority of it, a 5 is definitely plausible.</p>
