High school grades when transferring

How much do high school grades factor in when you’re transferring? I got into a UC before this, have decided I hated my major, so I’m going back to a community and transferring from there. My high school grades were below par, maybe a 2.8 UW? 3.16 W. I have a 3.12 from my UC and 15 units with one C on my transcript from college alegebra, I’m involved in school and other stuff also. I hope to raise that to at least a 3.4-3.5 by the time I apply with 33 units. Will my high school grades make it hard for me to be accepted? I have showed an upward trend in my math classes as I got a B in a higher math class. Thanks!

Look up the school’s Common Data Set, section D. It will show if they consider HS info.
