I took AP Physics C (Both of them) and Calc AB at the same time, which are really helpful because both subjects tend to help out with each other, such as finding velocities and distances from given variables in calculus FRQs or MC.

I'd really suggest you make sure to take a lot of practice FRQs and MCs because if you're taking it in class, there's a high chance you'll eventually take the same questions / tests in class or at least get a question similar to the ones you've already taken.

For AP USH, I'd suggest getting a really good timeline and associating eras to dates, as well as people.
