re: The biggest problem in schools that no one is talking about

That's just it. If I need to come to class to learn, I will come to class.

I am the type who won't need to study as hard if I attend classes where the teacher actually teaches.

Unfortunately a lot of the gen-ed courses in college were wastes of time in the actual classroom. There were quite a few I just stopped showing up to after week 1 and still made an A. There were also a lot that I couldn't miss even one class without being lost -- regardless of the teacher's attendance rules.
