4. Announcements April 23
Our office hours remain the same through May 7, 2002 (except I am out of town Mo., April 29).
The grades for the midterm exam should be available some time this week.
Check our website on how you can pick up Exam1 and Homework1 (and Homework2).
Submit Homework2 electronically, and deliver a hardcopy of Homework2 to Haili on April 29 or to me on April 30, The ODL problem has been removed from the homework.
Overhead Projector Problem for Thursday
Note that the final exam takes place in 104C!
A review list for Part2 of the QE will be available this week

5. Announcements
There will be a meeting for students interested in taking the QE Exam directly after TH’s class. If you cannot attend this meeting, visit me during my office hours instead.
Checkout MS SQL Server 2000 CD from the department and install it on your own computer, if it has enough disk space. There will also be a dedicated machine for each group in the fifth floor.
Group Memberships for Project2 will be finalized by Th., March 28
I want to talk to all members of Group3 directly after today’s class!
