You guys of answered yourself.
You want to go to Miami - and don’t put all your eggs in one basket. It’s not an easy admit although as you likely know, you can go to Miami Dade and transfer as they have an agreement.
But based on that you want to live at home, you are really setting yourself up only for Miami area schools - so it’s early but you’re probably borderline for UM. There’s also FIU where you’d be likely, and Barry which is a safety.
I get wanting to live at home to save - but if that’s the case, I’d recommend going to Junior College.
Going to college isn’t just about going to class - it’s about the entirety of life, from joining clubs, eating in the dining halls, and having late night study sessions. You just lose too much otherwise.
There’s lots of other schools to suggest to you - but at those, you couldn’t live home.
Other nearby, but not local, schools that might fit with your marine background are Eckerd and Florida Tech. If you wanted a more traditional college like Miami, but obviously an uber safety, it would be Tampa.
Good luck.
