Don’t listen to some of these people. The answer is it honestly depends. I learned WAY more in AP Chemistry than I did the first semester of college chem, and I go to a good school. My high school just did a good job teaching it I guess. As for calc, I had A’s all throughout AP Calculus, and I found that it basically was the same level of difficulty as all my other Calc courses (multivariable included). If you liked AP Calc AB, odds are you ae going to be extremely successful in all the calculus courses and probably beyond! So don’t sweat it! I was in the same boat last year and trust me, it’s nothing to worry about
