What do you think about my chances at Cornell?

High match for Cornell, only because (fortunately for you) it does not care about the Writing portion of your SAT.

…Actually you may well get into Cornell with a little luck!

How much would applying Early Decision help my chances with Cornell?

write some good essays and you have a decent chance at all mentioned (well stanford is a reach for everyone tho)!

Your ECs are pretty mediocre for the schools on your list. You’ll have to find a way to differentiate yourself somehow through your essays. Stats are in line for Cornell ED but again you’ll have to have essays and recs that set you apart. Good luck!

Stanford-high reach for anyone with that 3% acceptance rate lol
Carnegie Mellon-match
University of Pennsylvania-mid reach
UC Berkeley-high match
Brown University-low reach

A lot of the colleges only look at Math+CR so a composite of 1550 plays very well into your favor. I admit your EC’s are a little on the weak side. Hopefully you expand upon some of them more through your resume. Assuming your essays and rec letters are strong, I wouldn’t consider any of those colleges you’re applying to out of the picture. Best of luck:)

Stanford - High Reach
Carnegie Mellon - Low Reach
University of Pennsylvania - Reach
UC Berkeley - High Match
Brown University - Mid-High Reach

Kind of basic EC with no real zing. Do well on essays.
