The Classroom 3 is an adventure game, and this game instruction is from www.flash-games.net. Your main objective in this game is to cheat through series of tests. To do so, you have to get near the Geek (yellow), hold the LEFT MOUSE BUTTON until the cheat bar (on the right side of game screen) fills to the top and get back to your place. The teacher (red) is your main enemy. While trying to cheat, you have to avoid his field of vision at all costs. If his field of vision turns red, you will be caught. Best luck!
