If, after seeing your exam tomorrow, you are worried about how you are doing, come and talk to me in the office hours (like I said, it would
be wise to talk to me before taking any drop decisions).

Finally, if either of the students who ranked at the top of the 471 or 598 list can guess who they are and send me  an email I will buy them a geek present
(read "a book") for doing well *and* being brash. (I promise not to subtract any marks from your total even if you guess wrong ;-).
