Jimmy Corno asks:
Should project updates be written as updates to the original document, or should they be entirely self-contained (i.e., should I describe the project again)?
UPDATING YOUR PROJECT:
I suggest you use the same document, increment it by the week's work (also edit the preceeding text, if your ideas about the project change along the way), send the updated file to me every thursday. In this way by the time the course ends, you will have the project written up in its entirety.
