Should I drop APUSH?

My schedule right now is:
AP Physics
AP Environmental
AP US History
AP Language and Comp
Leadership
Wind Ensemble (Varsity Band)

I’ve been super stressed out because of the large amount of reading for APUSH. I pretty much flunked my first quiz and I did poorly on my first test (I have an 85 now, but he didn’t enter in my test score yet). I feel like APUSH is affecting how I do in my other classes, but I’m afraid to drop it because I’m afraid colleges will think my schedule is too easy without APUSH. I finished all the math classes available at my school (took Calculus as a freshman and Prob and Stats as a sophomore). Because of this, my math skills are lacking and my PSAT score was average. I was wondering if it’s worth it to drop APUSH (if I do drop it, I’ll have more time to study for the SAT) but will it make colleges look down on me for my schedule? Thanks!

Edit: I’ve passed the deadline for adding a class

Can you dual enroll in math? If you want to go into anything STEM related, you should keep taking math classes. If you aren’t interested in APUSH, and it’s causing you stress that you don’t think you can handle, you should drop it. Make sure you still take a US history class.

I am planning on taking Calculus at a private college my senior year. I’ve passed the adding classes date for my class, so I’m thinking of taking it online… would that look bad?

It depends on how competitive your college targets are. Top tier will like APUSH and care less about APES. What possible major?

I’m probably going to stay instate, but I’m eyeing Pomona.

See if you can drop APES and keep APUSH.
Not having math for two years because you took calculus in 9th grade is going to look very bad. Look NOW at what your community college offers for Spring and make SURE to register for the Spring. Take Calculus 1 this Spring, Calculus 2 and 3 next year. Even if it doesn’t appear on your HS transcript, just have the CC send your transcript to your colleges. A one-semester lapse will not impact your odds, a one-year lapse will.
Have you reached level 4 in a foreign language already?
(Pomona, assuming you mean Claremont, not CPP, will expect level 4 if not AP.)
