The main functionality of the app is to allow teachers to draw the pupil to be questioned. Pupils who have already been questioned are excluded from subsequent draws until all pupils have reached the same number of questions. The number of queries for each pupil is stored. After each draw, the teacher is asked to confirm the draw or to move on to the next or previous pupil in the class list (useful when an absent pupil is drawn). The teacher can create an unlimited number of classes and students
