I think you have a very interesting profile, with great ECs, and good academics despite having dealt with undiagnosed Crohn’s disease. I’d say you’ve got a great plan. I think that you have a chance at Northwestern, and also at Emory. Certainly you’re likely to get into both U Ga and Georgia State.
You might want to retake the ACT. The reason I say this is that I presume that the science 29 was your lowest section, and it is very easy to raise the science section score. All you have to do is either do the science sections in The Official Guide to the ACT book (doesn’t have to be this year’s), or download retired ACTs that you can often find on the internet - these are legally in the public domain - and do the science sections. Once you’ve familiarized yourself with all the ways in which they present the data, you should do much better on the science on a retake. But frankly, your 1520 SAT and your 33 ACT are probably good enough as is.
