Transfer from UCSD to UCLA

So I’m an undergraduate that transferred to UCSD from a CC. I was also accepted to UCLA but decided to go to SD instead. I regret that decision and want to transfer to UCLA. What’s my chances they’ll accept me again? Any advice?

I have no actual sources so don’t quote me please, but from what I’ve heard at the CC I came from, they really wanted to make this point clear; that it is quite difficult to transfer between UC’s and that you must have substantial reason to do so. They stressed the importance of choosing the right school because once you decide, it is almost impossible to switch. Like I said, I might not be the most reliable or accurate source but this is what I was told. Of course you can still try. May I ask why you want to transfer? I just got to UCSD this fall and am enjoying myself quite nicely.
