You could also consider some place like Tulane University in New Orleans. It’s a private school. tuition & fees runs ~$50,000/year (but look it up at the website for the actual #s). Total student body is ~13,000 with ~8000 or so of those being undergrads. I think they have a football team. It’s competitive to get in, but not as competitive as Oxford.
By the way, Oxford is a reach for everyone. It’s not easy to get in there. And the UK university experience is different than in the US. Do some research on that before you decide whether or not to apply to a school overseas.
However, when I look at your list of schools you’re interested in learning more about, the #1 factor that’s common among all of them is a big football program. Trust me when I say this…a big football program should not be your biggest reason for picking a university.
Aside from Ohio and Michigan, most of the rest of schools seem to be in states in the lower half of the US, which would lead one to think that you’re looking for a school with decent weather for a good portion of the school year.
If you’re interested in UCLA and if football & a big school are top priorities, then you should consider USC as well. However, the neighborhoods surrounding USC are terrible. As in, unsafe to venture into. Compton. Campus security at USC is good though from what I’ve read.
If you’re interested in FSU, then you should look at Univ of Florida as well or other public universities in Florida. You could also consider University of Miami in Miami, FL. It has total enrollment of ~17,000.
1 of my coworker’s daughters went to Clemson in South Carolina and she LOVED it there. Truly loved it. Joined a sorority, had a wonderful time, and got a great education.
