Transferring into UT Austin

Currently I’m a senior in high school. So far my plan is to go to Lonestar community college for a year, then transfer to a university. At the moment I’m really leaning towards UT. I will be graduating high school with about 21 hours already and only hope to be at Lonestar for a year. My question is what are my chances in being accepted into UT as a transfer from a community college?

What about PACE or CAP programs? HCC? UH?
