Looking for really old pc game

[Oldgamer97]

I am trying to remember the name of an old pc game I played as a kid. You walk around as a high school student trying to save the school from a mad scientist and his robots. You walk room to room finding robots and they ask you questions and the goal is to figure out which one of the robots is actually the mad scientist before midnight. This game was made in either 1980's or earlly 90's. Any ideas?
