Not everyone had the same experience as you, is that really hard to understand?

I had 20-30 hours of scheduled class hours alone every semester of undergrad and probably averaged a minimum 15-20 hours of classwork outside of class on an average week (just weekly assignments, any exams or big projects would pump those numbers up). This is not just me being bad at managing my time or doing extra work either, most of my classmates were spending even more time on class work.

With that said I'm not saying it was unmanageable, but it definitely made for a busy schedule if you wanted to do literally anything but classwork (e.g. clubs/jobs/extracurriculars).
