I personally used Barron's which was helpful for both the exam and the class. But I also used
PR as well for a quick review. I would say use Barron's if you have a lot of time. It over prepares you but at least you'll feel confident. If read well, as long as you don't screw up the essays, you'll guarantee yourself a 4 or 5.
PR is a little easier to read and is good a month or two before the exam. You should know your stuff but
PR doesn't go quite as in depth as Barron's. Both are pretty good books though but they cater to different types of students. Smart move not getting 5 steps. I used this one in class and felt it was wayy too general.
