The second midterm has been moved to April 19 (instead of April 14). I (Karen) will be around on the (holiday) Monday April 18 for questions in person 1pm to 3pm and by email. Most of the building doors will probably be locked so you'll probably need to go in the door for the big computer lab then through the computer lab itself and through some double doors to the basement of the classroom portion of MCS. Then just find a staircase and come to the first floor.
Karen's office hours Wednesday March 16th are cancelled.
The first midterm has been moved to March 3 (instead of February 24).
There is a typo in question 2.36 c. The second sigma should have an argument of x.
