I won't be extending deadlines in this class unless there is a class-wide emergency, CSNS is down, or some other problem outside of the control of the class as a whole. 

To make the deadlines, you need to work on this stuff every day. Don't wait until the day the assignments are due to try to do it --- they are designed to be too hard for that. 

This isn't an easy class. I am intentionally making it challenging.
