Online classes ruined my gpa..

I feel horrible about myself. My GPA dropped to a 3.1 after getting a C in gen chem 1 because I had to basically teach myself. Im a community college student(Biology major) who really wanted to go to UC Davis, UC Santa Cruz, Or the University Of San Francisco. I’m sure my chances at Davis are over now but I’m hoping I still have a slight chance with my other choices. I bought my own computer now so thankfully I won’t have to share with my siblings anymore and I can focus on getting my gpa up, but I was supposed to start applying this fall. Do I even have a chance anymore?

Forgot to add- I’m taking intro to physics and calc 2 over the summer so I’m hoping this will bring my GPA up.

You should still apply, but how does your GPA drop to a 3.1 from ONE C?

GPA wasn’t that high to begin with. I had plans of doing TAG since the requirement was a 3.2 but obviously I can’t do that anymore and I ended with an A in organismal biology, a B in calc 1, and a C in gen chem.
