A study guide includes a housing with a screen and a removable cartridge. The cartridge provides textual material including a plurality of questions and a set of answers for each question. The textual material is displayed on the screen and the user then selects one of the answers in response to each question. A microprocessor in the housing tabulates the answers and on demand displays a score of the total number of questions and/or the number of correct answers.
