If you had a YELLOW test, check your answer to MC#5. The correct answer was A, but the key had D as the answer. So if your answer was A or D, please return your test to your TA for correction. If your answer was B or C, you are not affected by this mistake. If your answer was A, your MC grade will be increased by 5 points; if your answer was D, your MC grade will be decreased by 5 points. The solutions for test 1 are now available at the Noble Library Copy Center. 6/04 Late additions in tonight's HW to Chapter 5 Problem 9.
