Top 10 hard to say

It depends on a lot of factors. The stats is strong, but not exceptionally strong for the application pool of the top 5, 6 schools. Top 10 schools put a lot of weight on intangible factors.

What about major academic awards? talent awards (music, arts, sports, etc), leadership? voluteering?

15 APs is very impressive, but needs to be compared to other students in the same school to put into context.
(But by any measure, 15 is quite a lot).

Top 12-20 should be quite safe.
