> If someone is caught cheating how do I know they didn't cheat in previous classes, but got away with it?

I could be wrong but I don't think this happens that often. If you cheated enough not to understand what was going on in calc 1 may god rest your soul as 2 and 3 are going to be downright impossible. For those types of classes you need to mostly understand the material even have a chance at cheating successfully.

They're not just talking about prerequisite courses. If someone is willing to cheat in a Comp Sci course, they're probably willing to cheat on a Literature class.

The amount of cheating and the industry around writing papers for others might surprise you.
