Transferring from a CSU to UC

I am in CSULA right now and I want to major in Astronomy. I researched and found some really good Astronomy major colleges but I am not quite sure if I’m going to make it in since my GPA is just average.

I am just wondering what are my chances of getting into UCLA or UCSD and if my chances are low, what can I do to make it higher for the next time I want to try again?

Post in the UC transfer thread.
