Quiz/Homework grading:
40 HW at 2 pts each, dropping five --> 70 total HW pts.
At least 15 quizzes at 10 pts each, dropping at least four --> 110 total quiz points
10 miniquizzes at 2 pts each --> 20 total miniquiz points

HOMEWORK COVER SHEET:
Here is a link to a helpful sheet that you can print out, fill out the information, and staple to your homework to hand in. If you have any specific questions on the homework that was due, the "Comments and Questions" line is where you can put them to be sure I see them, and will address them, either in class, or I will ask you to discuss with me privately. If you don't use the cover sheet, that's fine-- I will just assume that you had no questions with the homework.
