If my freshman grades were unsatisfactory, how greatly would it effect my chances of being accepted into a prestigious college such as MIT, Yale, Stanford, Etc? I am aware that some colleges look at your life away from your class performance such as what clubs you participate in and programs your part of.
You pretty much fucked up your life and your chance to get into the Ivy League + MIT if you're shit on your first year and those won't look on your social life or what clubs or fraternities you joined
I'm sorry to say this though, but unless you changed the way to view mathematics completely, you won't get accepted by the big ones
