What would make a UC revoke admission

I know its very early in the second semester of my senior year but Im beginning to stress. Ive never had a C before and i currently have a C+ in Calculus. Im nearly certain that I will be able to bring it up to at least a B, so i know i shouldnt be stressed, but would a C be reason enough to revoke admission.

UC’s require a weighted GPA of 3.0 (unweighted for UCLA/UCB) and no D’s or F’s. You are fine.

Nah my friend who got into UCSD last year had a C in his second semester of senior year.
