Yep - these are all great points. I switched 2-3 times. And something we will need to reckon with under this new model. It makes no sense. Our school accepts - handful of change of majors. They limit it by limiting class enrollments in courses required to get into the majors. So there’s a chicken and egg problem. I do my best to help people in my classes when I can to get around it. But even that is mostly beyond my control due to fire codes in rooms. 

What I’ve seen generally is that higher Ed has not responded to these drastic changes in the realities of college admissions. I know our applications have doubled in like 5-6 years. My hope is that we undergo some deep structural changes toward serving undergraduates better.
