There should be increased settings for teachers to manage in the games. For example, if a student gets an answer wrong in time to climb, it turns red indicating the answer is incorrect but still advances the student up the mountain. a teacher should be able to change the settings so students do not advance if they get the answer wrong, and select that they want the student to be asked that question again later in the game until they get it correct. Im sure there are lots of other settings teachers would like to control!
