let’s think about this in terms of expected value. Suppose if you cheat successfully, you’ll get an A and hold a 4.0. If you cheat unsuccessfully, you get a 0 and are expelled. If you don’t cheat, assuming you get a B, you’ll have about a 3.95. Let P be our probability of success.
4P+0(1-P)=3.95
=>P=0.9875

So in conclusion you should only cheat if you think you have about a one percent chance of being caught (or less).
