is to be turned in Wednesdays by 5pm.
There will be a drop box in the basement of APM.

**Disclaimer:**
I will try to get the homework assignment on the net in time.
Due to time and other limitations, this may not always be possible.
The fact that there is no assignment posted for a particular date does
therefore NOT necessarily mean that no homework is due.
