AP Psychology and AP Human Geography

Hello, I know this is early but I plan on self-studying these APs next year. I’m just wondering what textbooks/prep books I will need. Can you just use Prep books to get 5s? Thanks</p>

Barrons for both, but also PR for Human Geo. And yes, that is all you need.</p>

Thank you. I thought this was the case but I was just making sure I did nto need a text book.</p>
