Physics 7B and/or CS 70 over the summer?

Hi! Would it be more beneficial to take Physics 7B or CS 70 over the summer, and how doable is taking both? I’m currently an EECS freshman but am considering switching to a different engineering major.

Physics 7B is required by all CoE majors, while CS 70 is only required by EECS. So Physics 7B would be higher priority if you may switch to a different CoE major.
