Change the fact that your GPA and the name of the school on your degree and maybe cheating will actually hurt you. Cheating does not hurt yourself unless you let it. Most of the classes, are useless. UC's teach theory. They teach what can be done, not what you should do. A good teacher will not have cheating because students will want to learn the material because they back theory with substance. I know my favorite CS teachers were there for us to learn and tought in this way.

Also, with CS I've "cheated" according to the definition, but I have learned more, working and discussing code and how to implement it, with friends than I have learned on my own.

There is a way to stop it. Make it interesting.
