Here is the link to the UC TAG matrix which should answer most of your questions and what GPA is required to TAG to each of the 6 campuses.

Regarding GE’s, here is the link of the required GE’s for UC’s:

You can use assist.org and type in a local CC and then your desired UC campus to see what are the GE requirements and major requirements. If you start CSULA, you would have to try and match the CSU GE’s with the UC GE’s which are different.

If you are set on transferring to a UC, I would not attend CSULA, but start at our local CCC. Much easier to articulate the correct courses.
