I must apologize for not being available for testing; school has priority.
No you mustn't! Except for those of us getting paid, no-one should feel obliged to help out. Not contributing just gets you a score of 0 and any contribution at all makes it go up. There are no negative scores. ;)
The good news, however, is that I think I did well on my calculus exam.
Congrats!
