I’m sorry. I wonder if it was your choice of major. Those majors are very competitive. My son is still getting emails from some schools that must not have had enough applicants. I’ll see if I can get him to show me the list. Here are some that are sending him emails that say they are still taking applications.
U of Redlands
Unity College (probably not your thing but mentioning anyway)
Northern Vermont University
Johnson & Wales (not sure it has any of your majors)
Ursinus (nice small liberal arts school with CS. Know someone who went there for CS and is in grad school for AI now.)
Maybe UMass Dartmouth but not sure - he got an email from them
New Jersey institute of Technology
University of Bridgeport
Hampshire College maybe, not sure. He got an email Monday.
Morovian University maybe
I’m pretty sure there are others, too. Maybe other people can post and let you know which schools are still taking applications.
I’m very sorry that happened to you. One of my friends had the same thing happen to him and he ended up actually going to one of the schools above and did very well for himself. He never knew why he got rejected from everywhere except that one school in spite of having a high GPA and test scores and lots of activities. But it worked out and he met his wife at that school and is very happy he went there. His kid goes there now.
Anyway, good luck and try to not let this get you too down. It stinks now but I think if you are able to act soon, you can still apply to other schools that would be thrilled to have you.
