A system for using a computer to record and grade answers to problems that have numerical answers, where problem statements have alphanumeric parameters that are replaced by digits taken from an identification code. Students are asked to solve the same problem statements with either the same or distinct identification codes; in the latter case, each must perform a different calculation to get the correct answer. Each student is provided with a transportable memory means such as a floppy diskette which is specially programmed to prompt for answers and record them in a computer-readable form. Grading then consists of using said memory means as input to a computer program that reads the currently recorded answers, determines which are correct, informs the student of the results, and records the results on a system file which provides current information for the instructor but is inaccessible to the students. Incorrect answers can be reworked and resubmitted as needed during a time period specified by the instructor.
