I'm self-studying AP Psychology this year, and I want to know what advice does anyone have pertaining to self studying this particular course. I've already bought Barron's AP Psychology, but what else should I get to study for the exam? Any online resources? What is the exam like, one of the toughest or one of the easiest? Also, what topics should I concentrate on the most? What score do I need to receive in order to get a 5?
