Hardest AP class you took?

Hardest- AP Chemistry, I just can’t even comprehend concepts that are so far from the sensible reality we live in and my brain was literally rejecting the material we were learning, did horrible in class and on test day.
Easiest: AP English, teacher was chill

AP biology

Hardest: AP Lang/Comp because of the multiple choice, not the essays.
Easiest: by far AP Statistics

hardest: AP World
Easiest: AP World

I’m a freshman and I’ve only taken one ap so far. AP World is pretty easy. The tests and essays are a breeze. I’ve gotten 70s on the practice tests.

AP Physics 1 but only because my teacher taught it weird-- if it were being taught normally it probably would have been easier.
