A series of basic questions on medical bacteriology for the 1st grade of medical students was prepared on computer display (computer quiz). This computer quiz consists of 163 short sentences with either right or wrong content. Students can challenge the computer quiz as many times as they wish whenever students are free from their formal curriculum. A printed list of questions and their answers was handed to students in advance because the computer quiz was opened to students in advance of concomitant lectures and students had no previous knowledge on which they might relied. This computer quiz might serve not only as an alternative of conventional methods for evaluation of progress in students' studies but also as a convenient tool to let medical students efficiently memorize the outlined index for basic bacteriology.
