scantrons are easy

At least, the kind that are in use in schools across the country are. On those, there is a specific place you fill in one of the spaces and it tells the machine that the slip is a key and to score all subsequent ones in accordance. Reason I know is because one student in biology class did that and screwed up several people's test results. Teacher caught it because several students that normally made A's suddenly made D's and F's.
