How did you pull a 5.12 in high school or anywhere on a 4.0 scale where AP courses, at most boost your GPA by 1 point.
Anyway, getting into college is the easy part, staying and making something out of it is up to you.
You should find out the retention rate for the uni you're going to attend. Just go to google and do a simple search or visit the college's website and look for it. You'll see that a lot of people will drop out from the getgo. Looks like the U of C is small, you atleast you won't be too busy with being distracted by the social life
