Abstract: The present invention relates to a method of information retention of learned material which displays a question on the user's screen at regular intervals, according to certain criteria, including a weighting system. This process consists of electronically reading the questions that will be asked to the user, shuffling the questions, sorting the questions according to criteria or a point system, preparing the list of questions, displaying the most popular questions, one after the other, allowing a maximum time if necessary to answer the question, adding or subtracting zero, one, or more points for each answer given by the user, linking and saving the point(s) assigned with the question asked or to the group to which the choice question belongs or to the question linked to the answer or to the group to which the question linked to the answer belongs and to determine when the next question will be displayed.
