Would it be possible, that if I work my tail off in community college, could I be accepted to Stanford?
Stanford is not an Ivy League school. So I’d say no.
I know one Ivy does take A students from community colleges, not sure if all would do so.
Yale student here. I know a few students who transferred from community colleges, but I’m not exactly sure what they did to get in.
This link showcases the profiles of a few transfer students and might give you a better idea. I spotted a few community college admits: http://yalecollege.yale.edu/new-students/transfer-students/transfer-student-counselors-trocos-2016-2017
Princeton currently does not accept transfers but I believe the rest do? It’s very hard though.
Stanford is in the Pac-12, not the Ivy League.
Stanford admits very few transfer students, usually a few dozen per year. However, its press releases indicate that many of them come from community colleges, often from non-traditional backgrounds (e.g. military veteran).
