Quit a four-year university, started at a CCC then transfer to UC

Hi, really thank you for replying my post. I am sure that some of my 33 credits taken at my previous university cannot be transferred since they are GE class exclusively offered at that university. But some of the GE classes, for example, introduction to Psychology, may be transferable. In that case, I am wondering how will they calculate my GPA? Because I took Introduction to Psychology at my previous university and got A-, then after going to study in CCC, for the similar class, I got A. Will they take the average of A- and A? Or will they just replace A with A-?
Thanks a lot for your help!
