Physics remedial on-demand classes in the field of mechanics have been conducted for two years. Students in the class have been assigned on the result of the placement test immediately after admission. Each lecture consists of a series of video lecture, careful reading text, and exercise, followed by assignment. The assignment was submitted as many times as needed until it passed. The classes with the same lesson content were opened two times in a year, both in the first and second semesters. The acquisition status of the classes and progress of improvements on the lectures are reported.
