YOUR SAT IS LOW ? :O From what angle?
Your SAT Score is good, and your ECs are fine too !
Only thing I'd worry about right now would be your essays, they are VERY important.
Also, if youre a URM + First Gen, it increases your chances I believe.
So Id say you have a very good chance at Dartmouth. Prolly in!
Focus on the essays and
All the best!
Chance back please ? Chance an Indian for HYPD + Cornell + MIT? (Will chance back)
