Can your family afford your EFC? Run a few of the net price calculators-- today- before you fall in love with any more schools. Princeton is likely to be the most generous, Pace the least. So if you can’t afford Princeton, the “need only” colleges on your list are a waste of the application fee.
And why would you take both Calc AB and BC at the same time- does your school even allow that???
Your profile is great. The answer is not “what you should do to make yourself more attractive to top schools”. The answer is “figure out a list of schools which are going to fall in love with you just as you are and which you can afford” . Keep a few lottery ticket type colleges on the list if they are affordable, and focus on getting excited about your match schools.
I am a huge fan of UIUC btw but Illinois residents would think you are nuts paying out of state rates when you have some fantastic SUNY options instate. I’m sure you’ve heard of kids who were admitted to U Texas at Austin and decided they’d rather go to U Albany “because it’s close to NYC” which is sort of hilarious. Well- to a kid in Chicago, you applying to UIUC is sort of the same dynamic.
Have you looked at Missouri M&T? Rutgers?
