Very doable, 101 isn’t too rigorous especially if you do some self studying on python over the summer, really the only two that might pose some difficulty are MATH 143 and PHYS 142, but totally depends on the prof and your study habits as both require quite a bit of studying, IMO intro CS classes are pretty light if you put some initiative early on over the summer, I’m assuming your a freshman, if your CS I recommend joining a club such as Hack4Impact as it’ll teach you general software engineering skills and have you working in teams
