Classes in Community College for credit?

Hello, can I, as an international student take online classes from a local community college for transfer of credit after confirming enrolment in UC Berkeley , or do I have to wait for the summer after freshman year to do so?

I have 0 AP credits, so I’m thinking of taking some classes online through a community college to earn some credits before going in. ( Also, how important is having credits before joining Berkeley? Will not having any disadvantage me during course registration?)

I will be joining the L and S in fall 2020 as a prospective CS major, so:

  1. from which community college, and
    2)what courses would you recommend me to take over this summer?

(P.S. , I’m looking to knocking off some breadth requirements)
