you're asking a forum of people who know nothing about how many units you're taking, how many prereqs you've done, what your major is, when you will finish IGETC, and what your grade trends are like?
If you're applying to UC's in this cycle, you will not be accepted to any TAG programs and most likely not to any UC's. Your GPA is too low for the minimum requirement and UCSD's filling period for fall is over at the end of the month, you cannot raise your GPA before then.
Let me google that for you
google is a really good tool, you should use it...
if you really have your heart set on going to UCSD you should stay an extra semester/year and get your GPA up to a 3.0. You'll see on the TAG matrix, that SD accepts winter transfers, if you can get your GPA up to scratch by then you may have a chance.
If you feel as though this task is too monumental or you don't feel like staying any longer at CC you should think about going to a CSU, their standards for accepting students are much lower.
But most importantly, you should go talk to a counselor.
