Realistic chances of transferring

Hello to those who are reading this!

I just completed my first year at Cal Poly Pomona and to be honest, this school just isn’t for me. I’ve always dreamed about going to UC Davis and was wondering if anyone could tell me what my chances of transferring to another UC are. I’ve heard that while it is difficult, it is not impossible. I currently have a GPA of 3.4 and I am majoring in sociology. Please feel free to reach out to me if you or anyone you know has had any similar experiences, I would love to know your thoughts!
