Discussion of Quizzes

• We will have our next quiz covering Chapter 5 on Monday, April 12
• We will also have quizzes on Chapter 6 and Chapter 7 as we move through the Unit B presentations, probably on Monday, April 19 and Monday, April 26, but these dates may be moved slightly after I get the Unit B proposals on Friday. I'm trying to be as flexible as possible to accomodate your hectic schedules.
