I am also TAG’ing to UC Davis for CS as well. Courses on ASSIST basically lists all the prerequisites required/recommended for a major. All I can say is I highly recommend you do the physics courses regardless. This way, even if your TAG is not accepted somehow, you still have a chance of getting in through regular admissions.
Also,
“Transfer students are strongly advised to complete as many preparatory courses
as possible for their major before enrolling at UC Davis. Preparing well for the
major helps students move efficiently toward graduation and significantly
reduces time to degree.”
Quoted directly from the ASSIST page for CS major.
Even if you got in by not doing them, you may end up taking them anyway after you transferred. And since these are lower division courses, it’s only going to take your time away from taking more upper division courses.
TLDR: Take the physics courses. It’s safer for you that way.
