UC admissions has made some changes to their admissions policies for both freshman and transfer students due to the coronavirus situation. I have included the link for all of the information directly from UC admissions, but I thought I would share it here for any other UC transfers who are curious about things like pass/no pass credits, etc.

Pass/No Pass: UC has temporarily gotten rid of the 14 semester/21 unit limit for pass/no pass credits taken in winter/spring/summer 2020 since many colleges are switching to pass/no pass or credit/no credit grading right now. However, whether or not pass/no pass credits will be counted for major requirements is still up to the individual campuses. It does say that they will be as flexible as possible.
Cancelled Spring Courses: They also state that if you were planning to take a class in spring term but it was cancelled, they will allow you to take the course in summer instead as long as you still meet the minimum admissions requirements for UC transfers (60 semester/90 quarter units completed, 7-course pattern, and 2.4 GPA).
SIR and Transcript Deadlines: They will not be changing the SIR deadline from June 1st, but they may accommodate individual requests from students who need more time to be able to pay the deposit fee. Also, they still want you to submit your transcripts by July 1st if possible, but admissions offers will not be rescinded if you miss the transcript submission deadline.
