Change of heart after orientation, possible transfer to Penn State?

So in early April I was having an extremely difficult time deciding between St. Bonaventure (a small, bit less selective school) and Penn State Main campus. On April 28th I enrolled at Penn State, and on April 30th enrolled at Bonaventure (I rescinded PSU as soon as reasonably feasible).
I felt that I had made the decision that would give me a better chance at getting a high GPA in order to position myself for dental school admissions, since that was the ultimate goal. I was never 100% on board with Bonaventure, and Penn State was always were I saw myself going, but turned away after seeing how large the freshman “pre-health” bio classes were. Other than the small class size, their is literally nothing I like about Bonaventure more.

So I went to orientation, and was not really impressed. I mean I appreciate the close community and the opportunity for legitimate interaction with professors, but it got to the point where I was sitting on a bench with my parents explaining how I was already considering transfering. It just wasn’t clicking for me. I old them I would give it one year, put my all into my work and build a very high GPA, but wasn’t willing to say that I would stay.

I went to the PSU transfer webpage and found that I might only be able to transfer after two years, not one. I don’t like this becasue I really think that Penn State is where I need to be, but can’t justify sitting out an entire year and reapply as a first year.

Do I have any options? Any and all comments are greatly appreciated and id love to give more info if helpful.

Thanks

** Note. I’m not entirely sold on dental school yet either, I’m technically at business student taking science pre reqs
