Winter classes for UC transfer

Hi, so I’ve applied for fall 2022 as a transfer to the UC’s. I was wondering how much it affects me if I’m taking 4 major prep courses in the winter? I have a 3.7 gpa and maybe a 3.8 by end of fall 2021. I contacted the UC offices and they said they don’t look at winter when they calculate gpa for transfers, and only look up to fall for gpa. Assuming If I got these major prep courses done before the JAN 31st TAU with all A’s, will it affect me? Or will they still be fine with it as long as they are all finished by January 31st? I’m a physics major btw.

3.8 will be the gpa they look at since they only look at your gpa up to fall. But taking major prep in winter or spring won’t affect you.

Yes, the UC’s will use your Transfer GPA at time of application in the Fall. Completing these major prep classes with good grades and reporting in the TAU can only help your chances.

Rule of thumb is that have as much Major prep completed at time of application but for many applicants it is not possible and completing these requirements by Winter and/or Spring is acceptable as stated by @thaoz1.
