CPP to CC to UCI

I am a freshman at cpp and I really don’t like it here. I’m planning on going to a cc my sophomore year and transferring to UCI(with tag) my junior year. The problem is that they won’t tell me which of my classes from cpp can transfer over. They told me they will only know once they look over my app. What should I do?

Also, I’ve always wanted to go the cc for 2 yrs route to go to UCI but my parents were against it, but after one year at cpp, I feel like I can’t handle it for another 3 yrs.
