Winter Storm Day Update

Well, once every 5 years isn't that bad....

Just a reminder:

• Everyone: If you missed an exam for a legitimate reason, it is your responsibility to bring a note for your absence and come to see me for a chance to make up the exam on the first day you got back. If you don't, you will get a zero for that exam grade. There will be no make-up exam once the exams have been graded and distributed back to the class.

• Group B's Lab. #17 will be held 1st PD tomorrow in Rm. 311 (weather permitting).
