How would taking BC Calc and AP Physics C in junior year stands out?

Cause I came from one of the top 10 high schools in China, and now I find out that it seems I have nothing comparing to the US top students. Even the toughest classes in my school and good grades don’t mean that much The only thing that I’ve got since I came here to prove my academic performance is the Princeton University Physics Competition’s honorable mention. I’ve lost so many precious time to adapt to the new environment. What can I do? Also, do you mean that I can still get into the top 30s? I’m worried that I may only be accepted to some state colleges now.
