I don’t know if your applications were already in. I do think that most are reaches for you. Rest assured that if you come out as a Comp Sci major, or better yet a double major Comp Sci plus Math, even if it’s from the least competitive state college, you will have more job offers than you know what to do with, and after that first job, it’s your work history you’ll be judged on, not the school you went to.
Did you apply to Penn State?
