AP Self Study for National AP Scholar

<p>I am a rising junior and I want to get National AP Scholar, but the problem is that my school doesnt offer AP Classes during a students freshman and sophomore year. This year I will be taking:
AP US History
AP Calc BC
AP English Language
AP French
I am planning to self study for the AP Music Theory since I took the ABRSM Theory Exam and did well on that. Also im looking to take the AP Chinese Exam since I am Chinese.
Do you think I can self-study the AP Environmental Science, AP Human Geo, and AP Physics B (Im taking Physics Honors this year)?
Oh and I know that those are 9 tests just in case I get lower than a 4 on one of them (which is most likely gonna be French since it is pretty hard from what I hear)
What are your opinions?</p>
