Would I get accepted if I take 3 years at my Community College?

I will be reveling an AST by the end spring semester, with 60 credits done, Golden four, AST, and 2.4gpa. I was rejected by all the CSUs I applied to, I emailed CalStateApply and they told me I didn’t include that I would be receiving an AST.
Since I’ll prob not get into a CSU I wanted, I was thinking that I could redo the classes I got low grades on and go for a 3.0+ and apply to a UC for next fall, is it possible? Will there be an issue for not doing it in 2 years?
I plan on getting into TAG, and I’ve had a low gpa in the first place because I was working a full time job and going to school during my first year getting Cs, but the last semesters I got received almost straight As.

There is no time limit attending a CC and then transferring to a UC, so if you want retake some classes where you received below a C, then do it and try for TAG. I would still consider some CSU’s in the next application cycle as backup.

Best of luck.
