As a Class of 2022 admit, I agree with @billcsho ; 3.5-3.6 is under their average, and doesn’t look as great as a 3.9. However-- I’ve been talking to a lot of people with friends with perfect test scores and gpas who didn’t get admitted. My advice would be over the next two years to join clubs, find some leadership positions, and use your summers wisely (internships, job experience, research, etc)–they also really look at your application essays, so make sure to take your time with those, and of course, legacy always helps. Best of luck!
