<p>@ucbalumnus: So in my case, I’m not sure if I wanna switch from BioE –> EECS or BioE –> L&S CS after the first semester: The requirements for each major is different since EECS suggests taking Math 53 + Physics 7A first semester, while declaring L&S CS requires Math 54 (not Math 53), but no word on whether or not to take Physics. Would you suggest anything in particular?</p>
