I only cheat if its a large lecture and I have absolutely no idea what the answer is. And when/if I cheat, I make sure the person I'm cheating off of has a clue of whats going on. So, I will compare an answer I know is right with their's and see if they got it correct as well.
Now, if that lecture has 6-7 different test versions. Then I'm SOL. :biglaugh:
I'm also very experienced in typing formulas and key notes into my graphing calculator. However, as long as they aren't banned from the test I don't see that as cheating, just using my resources.
