How many colleges have you attended? It sounds like you did 1.5 years at a Catholic college and 1 at a state school. Are you considered a junior at your current college?
You can’t apply as a freshman. If you transfer to another school you’ll have to send all your transcripts. What’s your GPA at each college?
Are your parents helping you pay for school? There’s a limit to state and federal aid, so your plan has to include how you’re going to fund your education.
I don’t think changing schools is the answer right now. I think you need to figure out how to succeed where you are first.
