Yes, and my other concern is that there are often specific course requirements for transfer students. Although OP states that he has enough credits for junior standing upon transfer, we don’t know if these credits cover the specified course load that UCs look for in transfer students. So I think we still need more info from the OP.
But, yes, totally agree on the safety. If we knew more, we could think about TAG which wouldn’t help with UCB or UCLA, but could make UC Davis, for example, a sure thing.
