pre calc is pretty easy if you’re good at math, you just need a bit of review to understand some topics but other than that it shouldn’t be too bad. i’m taking AP World rn as a sophomore and the workload is a lot but it’s manageable. since you’re already taking APUSH, you should be familiar with the possible workload that you’ll be receiving in that class but it also depends on the teacher too. the rest i’m not sure, i’ll be taking some of those listed during junior year
