Would it be realistic to attempt a CS minor with a CoC major (Not Chem E).
I plan to start taking cs preqreqs over summer, but not sure if this combination of upper divs in the future will end my life.
You can use some upper division CS courses for the “Upper Division Chemistry and Allied Subjects” requirement for the chemistry major.
