A number of students in the 4:20 class turned in the P quiz even though they were not in class. I changed all the grades to 0 -- but left the scores so that you can see what you got wrong.

Worse, at least three of you asked me if you could have the test count for you. You acted as if you took the test innocently and thought that you deserved a break because of the weather. It turns out that you got the same question wrong -- and wrong in the same foolish way. The worst academic crime is intellectual dishonesty. The three of you have lost all respect.

The current cheating has put the quizzes and other work in question.  I spoke to Dr. Pamula. We agreed to do the following.

For the MS students in the 4:20 section, the entire grade for the course will be determined by the final. Nothing else will count. 

If you believe that you did well on the quizzes or extra credit without cheating, I'm willing to talk to you about it. Please arrange to see me. I will ask you to explain your answers on the quizzes and your extra credit submissions. If I am convinced that you understand the answers you gave and the code you submitted, I will count the quizzes and extra credit for you. On the other hand, if I believe that you are attempting to bluff, not only will the quizzes and extra credit not count, a negative score will be assessed against you and subtracted from your score on the final.  

As indicated above, this applies only to the MS students in the 4:20 section.

Right. MS refers to Masters Students.
