Course Scheduling (Is it too much?)

I'm a Junior right now and am planning for my senior year. This is what I have, is it manageable?

AP Literature and Composition

AP Statistics (self-study)

AP Chemistry + Forensics + AP Physics (self-study)

AP Economics + AP Government (self-study)

AP Psychology

Intermediate Piano

**Should I take both exams for AP Physics and Gov?? The courses my school offers gives both exams for these classes

In total, if I took all these classes and AP Exams, I would have 10 exams. It seems like too much, but I'm decently confident that I can do it.

However, I am known to take on more than I can do at times, so other peoples opinions who have done this would be really helpful. THANKS!!
