It was a long night in the library and a large group of students were gathering to study for the upcoming AP Calculus test. As the hours dragged on, the group became restless and the Calculus teacher stopped by to check on them. And then it happened! The lights went out and one student snapped. There was a scream and when the lights came back on, the teacher was lying dead on the floor. Who did it? Which student is the killer? To find the guilty person, solve the following groups of questions to reveal 6 clues. --- The guilty is among you. Was it you?
