PLEASE do not email me homework early. (Also, do not be late, either.) I have spent about 10 hours today grading homework, and I am far from caught up. Much of my misery lies in the random order that I am receiving homework.
If they were grouped together, everything would go MUCH, MUCH more smoothly. This is easily achieved by your emailing me your homework on the day it is due. Not earlier. Not later.
