Is it hard to change major at UC Davis once transferred?

I applied and got TAG approved. However, I applied for Economics. I would like to change it to Managerial Economics. Now, it is too late to change my major for TAG. Is it hard to change major at UC Davis? If I do get to change once transferred, are my community college classes going to transfer as well?

Fairly easy to change majors. You’ll need to wait till your winter quarter to change it tho, but in the meantime you probably could take managerial econ classes as an econ major, so it shouldn’t matter if you stick in econ for a quarter(unless its major restricted).
