My most effective professors gave us the answers to the work we were expected to do. It was a much more effective way to learn than doing work and getting feedback to whether or not it was correct weeks later. Organizing academic work in such a way that "cheating" is even a concept is silly. You're there to learn, if you want to pretend that you learned I guess good for you but we need to just get over the fact that people can make it look like they did something when they didn't.
