The only “must take” my son cared about was FL requirements. FL was a nightmare for him in HS. He looked at the options in the catalog and whether or not he could fulfill the credits by taking transferable summer and winter classes at CC. He decided he could live with 3 semesters of FL.
As far as his major, he hadn’t fully decided what he would major in before starting college. His main determining factor was liking the school enough to want to spend 4 years there.
Many students don’t go in with a declared major, so I don’t get the sense that must take v.s. can take is a huge deciding factor.
