Now count how many you missed and multiple it by 4.4 pts.

• Each question was worth 4.4 pts each.• Total points possible on this assignment

was 400 pts.• On the front of the packet write out how

many you missed and what you earned over 400.

• Example: -35 questions * 4.4 pts= -154pts• 246/400, 62% D
