I had a similar application (took 8 APs and college-level courses in high school) and also tutored math mainly for community service. I was accepted into the engineering programs of the four schools I applied to (one of them being Northwestern University). I don’t have a feel for the “ivy” schools since I didn’t apply to any. I would recommend putting your applications together well ahead of time, and you should have a solid application for most schools. Many colleges take environment into account as well. For instance, a student who takes all honors classes in a school that does not offer APs will be looked at more favorably than one that takes 2 APs at a school that offers 15. Keep that in mind when you’re writing essays, etc. Be sure to highlight your drive to exceed expectations. Good luck!
