How difficult is it to transfer from UCSD to Davis after 2 years?

Right now I am undeclared and I want to transfer to Computer Science. If I fail to get in, can I transfer from UCSD to Davis and get into CS there (after freshman and sophmore years)? Thanks

Yes, you can do a UC-UC transfer. I suggest you post on the UC transfer thread since there far more knowledgeable posters in regards to the UC Reciprocity for your GE’s and transfer information.
