How viable this is probably depends on what you study, but I skipped most of the scheduled meetings (lectures) during college. At the most prestigious of the 3 universities I've attended (which seemed to have more respect for their students than the other 2) this was actually encouraged if you felt you had better ways to make use of your time.
Sure you do. The college day is broken up into many unrelated scheduled meetings, with high switching cost. Then you do the deep work after hours.
My post-graduation life is not so different. Maybe it suits my brain, but it's been OK. I like the work.
