At this school, each student has a rank. The ranks in order are: Ash, Fire, Coal, Iron, Copper, Steel, Bronze, Silver, Gold, Platinum, Diamond. Each rank has 3 sub ranks e.g. Copper, Copper-1 and Copper-2. Every action is rated of how many points it is worth e.g. Detentions are worth -10 (negative points reduce the student's rank) or best result in a test is worth +50 (positive points increase ranks). The lower the rank, the closer to expulsion.
