I think you should give your new school a chance first, you haven’t even started classes. When you say you aren’t happy with the school, what is it? It can’t be the students and teachers, as school hasn’t started. Why don’t you see how things go - you may meet some incredible people.
On another note, if you are already convinced Commonwealth is not the place for you, then you need a well thought out application strategy for next January. If you had mixed results with admissions this past spring and you are now applying to PA/PEA, recognize how long your odds are at those 2 schools.
