We introduced a web system for practice problems which provided immediate feedback into remote class and found the following things. The average score of the midterm exam was significantly higher than that of previous year. When we continued to deliver the contents of remote class in face-to-face class which was gradually restarted after the midterm exam, average score of the final exam in “the standard class” (“the basic class”) was higher (significantly lower) than that of previous year. According to surveys of questionnaire, the demerit we assumed when building the remote class was not off-target and our web system for practice problems and remote class got considerable support from the students.
