I’ll look over ur ap to give you some of my ideas. DO NOT TAKE TO HEART, THESE ARE MY IDEAS, PLEASE DO NOT TAKE OFFENSE
As for you, my friend, you demonstrate a lot of leadership in you extracurriculers. You’re test scores are very very good and your ush sat 2 may be a bit low, but NU will use it to help your application if needed.
Now lets steer clear of vagueness and get to specifics:
Math and chess club and want to major in economics? Doesn’t look that related.
How many AP classes total? a 3.75 gpa uw is definitely your weakness, I suppose you make that up with your hard classes…
Ok nice, JV bball but no Varsity? lol, at least it looks like you were involved to some extent physically
Played baseball in summer but not school year? Nonetheless you are very athletically talented, could be a plus but enough for recruitment?
How/why did you get to China to work? And teaching school children in India? Did your parents have a few bucks in their pocket to send you around the world to experience all these cultures or did you fund it yourself or work for it, etc. Hopefully not the former but still impressive nonetheless.
Other than that, assuming your essays are quite decent, you probably have good chance 75% of getting in ED.
Good luck and hopefully we can both get in!
