Need Help First Time Self Studying AP Psychology, Human Geography, and Environmental Science

<p>Hey guys this is my first time posting on College Confidential. I'm a junior at my high school and I'm going to be self studying AP Psychology, AP Human Geography, and AP Environmental Science. I need tips on self studying for these tests. What books should I get? How early should I start? This is my first time self studying too. Thanks! (I'm also taking AP Lang & Comp in a normal class if that helps with planning or anything.)</p>

<p>For AP psych, just get the barron’s book a month or two before the exam and study it rigorously. Helped me get a 5. Not sure about the other 2 exams since I have no experience with them. Good luck!</p>
