Well, in my case I never considered cheating as an excuse to anything. May be, I was lucky to born in a small country with 3 million people. I left my grades are to be an indication of how and where I spent studying. My grades are lower than the most other guys who explicitly cared about their grades. Even so, no one hasn't given me a shit about my low grades within 3 years of my career. May be because of in the end all what matters is that you do what you suppose to do good enough.
