How is AP Psychology? Is it an easy class to take?

Hey, guys. I am taking AP Biology and AP Physics next year (junior year). I wanted to take one more AP class.

I have already done AP Chemistry so I was thinking of AP Psychology. It is either AP Psychology or AP World History and I am not that good at history.

To everyone that got a good grade in AP Psychology, it is easy? My school doesn’t offer AP Psychology so I am going to self-study with Barrons. Do you think it will be a good class for me?

How hard is AP Psychology? Is it pretty much just memorizing all the information and using prep books and flash cards?
