Corrupted Academy

You play as a teacher at an all-girls academy. After falling on hard times, the academy headmaster has been forced to turn it into a testing ground for a new government experiment. By law, you and your fellow teachers will be allowed to practice "Free-use" without fear of legal repercussions. You are instructed to ensure that the students do not pass the exam until a certain amount of time has passed, so the experiment will have enough impact on the students.
