Cheating on Peer Eval?

<p>That’s what I am thinking. How do they know if we are writing by ourselves using peer’s name? Of course, I am not going to have a stress on cheating but I am scared of some people doing that. Also, the document says to give the evaluation paper in a stamped envelope but why does it matter if my peer is going to tear it anyways to get the paper out of envelope.</p>
