Students in my Spring 2013 classes: You can now check your grades online in Etudes. Login instructions are here. Remember to change your password!

Students wishing to add my Fall 2013 classes: If the section you want is full, add your name to the waiting list in PAWS. If the waiting list is full, come to the first class meeting anyway, because I may be able to add additional students at that time; those students will be chosen by lottery.
