I feel like that you have all the components to attend any of these schools however like everyone else said your test scores are holding you back. Shoot for a 33-34 on the ACT and you will be beyond good to go for Georgetown. However Harvard and UChicago are gambles and anything can happen.
Chance me back please? We have the same ACT composite score! http://talk.collegeconfidential.com/what-my-chances/1743092-nyu-and-georiga-tech-will-chance-back.html#latest
