Applying ED and doing the interview would obviously increase your chances of getting in.
Your GPA seems to be good and your activities, while wouldn’t act as a hook, is (I think) about average.
If I were you, I would focus on two things:
- focusing & building up on your current activities -> make your HOOK!
- TAKING THE TEST TO GET IN RAGNE with Wesleyan’s SAT/ACT score. -> while it is true that Wesleyan is test optional, with tons of other applicants with similar stats like yours, it would be hard to differentiate yourself with others (the Class of 2021 acceptance rate was about 15%!!). I think it would be best if you can get an ACT score between 32-34 and 2~3 SAT2 tests with scores 750+.
oops just read that you are currently in junior year summer break.
Try your best in getting your scores in range! good luck
