Is it too late to start self-studying for AP Psych now? I’m a sophomore and I’m taking AP Calculus AB and AP Euro this May.
It’s not too late yet since AP Psych is one of the easier tests to self-study, but you need to put a lot of time into it starting now. You should get a review book (Princeton Review or Barron’s is best) and try to get in as much information as possible. Online resources are helpful as well.
@parrish I’m a sophomore and I started reviewing for the test three weeks ago. (I already took the class but it was first semester so I forgot a lot). I think you’ll be fine as long as you use Barron’s and take a practice test or two!
I did not take a psych class in HS and crammed with a review book over one weekend and scored a 5. That only goes to show how easy the AP exam is. Which is one reason Dartmouth no longer gives AP credit.

I am self-studying AP Psych right now. It is not a hard exam to study for yourself. I bought Barron’s and Princeton Review, which are pretty good. Self studying AP Psych won’t take very long and is totally doable.
