Going to get a job during the summer
100 hours community service at a local food bank

I have a few questions:

  1. I plan on taking online summer classes to potentially replace my 3 Bs I got first semester. Will USC or UCLA be able to see that during admission? I know we self report grades, so do I have to report that I did summer classes in my application?
  2. Did I pass on too many AP classes? (I passed on AP science class my sophomore year, AP Lang and APUSH junior year, and AP Lit my senior year)
  3. If I have no chance, what do I need to do?
