I think for UW Madison and Rochester you’d be in the top 75% of applicants and will most likely be accepted.I think you should have a great chance at being accepted to UCLA as well. Your extra curricular activities look great and showing an upward trend in your gpa definitely shows improvement which is very important. However, your gpa will probably hold you back from Johns Hopkins, especially for your intended major (as they are very strong in the sciences). UChicago you should have a better shot at and match pretty well for the 25-50% of applicants but you don’t really show much leadership in your extra curricular activities. They want you to be dedicated to your activities and be active in them (preferably throughout high school). So I say that UChicago is a reach for you but you never know!
