A curriculum is created aligned closely to the state standards. This is broken down into tiny units called factoids, analogous to atoms in chemistry. The factoids are converted into question-and-answer pairs. These are placed on electronic flashcards so that they can be sorted according to the degree of mastery. There is a question on one side and an answer on the other. They are answered mentally. A user/student can choose from the options “Show again: Today, A, B, C, or Never” depending on his/her understanding of the question. A software system remembers each student as an individual and the status of each flashcard that the student has attempted to answer. There are five tiers in the classification system: school> year> subject> topic> and subtopic. A subtopic would contain from 10 to 100 flashcards depending upon the grade level.
