Senior Year Dilemma

Hey guys,

So I have a major dilemma in terms of my senior year schedule.
As of now:
AP Calc BC (zero hour class/before school)
AP Bio
AP Physics C
AP US Gov
Calc 3 (independent study with a teacher. Only kid in the class)
Student Tutor
Film and Lit
AP Study Hall
Student Gov (StuCo Class)

Last year I took AP Chem, AP Physics 1, AP Calc AB, and AP Lang (All A’s and 5’s) along with some other non-AP classes.

So my issue is that I feel really over my head right now. I definitely want to keep all of my math/science classes so I think that AP US Gov might need to go (time consuming class with a difficult teacher). I could either just drop the class outright (there would be no mention of it on my transcript) or I could possible self-study AP Stats (math is easy for me). I feel like that if I continue with my current schedule, my grades would likely suffer (I still have an unweighted 4.0). If anyone would be willing to spread their wisdom, that would be greatly appreciated.

School started last week and I have until this coming Friday to make any changes.
