Should the homework be mailed at certain times? For example should we have mailed in homework for modules 1-6 by a certain date? and so on..?

[NEAS: If you do the homework right after reading the text, you may need 5 to 10 minutes.  If you wait until the course is over, you will spend half an hour.  We don't have specific dates, since some candidates may have work responsibilities that take precedence.  An on-line course requires self-motivation and scheduling for most efficient completion.]
