bioE to EECS freshman courses

I'm an incoming freshman admitted as a bioE major, and I want to switch to EECS as fast as possible (yes, ik its hard). what courses are recommended to take? should i take chem 1A if its only needed for bioE?

right now, im thinking:
math 53
cs 61A
physics 7b
other breadth requirement

mainly chose courses needed for both majors; is that too rigorous? if anyone has done that transfer, please PM your course plan!
