I heard that it is 3.0 or higher for all UC’s throughout for senior year with no D’sor F’s but on UCI undergraduate admission it stated to maintain a 3.4 or higher and for UCLA it is no more than 2 C’s.
In the past for UCLA/UCB, it was 3.0 unweighted no D’s or F’s and no more than 2 C’s. For all the rest of the UC’s it was 3.0 weighted, no D’s or F’s.
UCI’s provisional admission contract is linked and it states a 3.0 weighted GPA for Freshman admits. Not sure where you see 3.4?
