Also, on the cheating not being a thing outside of real life point. a) it is - there are lots of things you can cheat at which is against the rules. Stealing for example could be considered cheating as you haven’t earnt the item you’re stealing. b) uni/college is not there to teach you real life. It’s there to provide you the materials to learn a subject. Don’t want to use those materials and learn? Well then you probably just shouldn’t be there.
