a flash card management apparatus has a progression of compartments that govern or direct which cards are reviewed at a given drill session . when the progression is ordered by card capacities , a given card will come up for review possibly at each drill session for the first few sessions , and then come up for review with ever decreasing frequency thereafter . the use of the management apparatus will assure that each card will be not only periodically reviewed , but also reviewed a fixed number of times before it is put on the side .
