I got rejected from my STATE school_ What am I doing wrong?

You didn’t make a mistake during application, you do when you refuse to appeal at UF. Sure, you may not be enarmored with it but it’s a good choice for a student your caliber. You want it as a backup if possible.
For what it’s worth I do think they made a mistake. For instance this year there were errors at some large public’s (not pointing the finger at any specific one) because some kids had Sat scores put of 2400 and others out of 1600. And if at your school a 1390/2400 isn’t unthinkable and the past ten applicants from your school had scores out of 2400 and the staff making the summary sheet only had 5mn… See where I’m going?

You can still apply to NCF. Public liberal arts honors college.
And FAU 'S Wilkes College is another small honors college with its own campus.

You could run the NPC on a few other colleges still accepting applications : Hendrix, Truman State, UMN Morris. Perhaps Gustavus Adolphus, St Michael’s?
