I think that you have a pretty solid chance. Your ACT and GPA are exactly where they need to be. Your AP scores are not on top compared to the kids that will be applying (though they are pretty high compared to the kids in the rest of the country).
Your extracurriculars are very solid, as well. They’ll like seeing that you were a varsity swimmer for 4 straight years, and it looks like you have done some good stuff for charity.
All in all, you have an excellent application, but lots of other kids will have applications that are just as excellent as yours. I would say that you have a 2 in 3 chance of getting in.
Go Irish!
Would you mind chancing mine?
