Suggestions on
Preparation and
Review If you have any questions, ask teachers or search online.

Requirements ・If you do not complete course registration by the day of the first class, you may not receive course-related announcements.
Inquiries about pass/fail decisions will, in principle, not be accepted. If there is a special reason, please make inquiries through your tutor or academic advisor.
・Grade revisions will be made only when a clear grading error by the instructor is confirmed.

Policy on Absences:
・Six or more unexcused absences will result in a failing grade.
・If you must be absent for an unavoidable reason (e.g., illness/injury/accident, bereavement, participation in events hosted or officially approved by the university, activities of university-recognized student organizations, disaster-related volunteer activities), you must notify the course coordinator by email as soon as possible, either before or after the class, and later submit documentation (e.g., a dated medical receipt, a public-transport delay certificate, a wake/funeral notice, or a certificate bearing the seal/signature of a club captain or faculty advisor). Only when all procedures are completed will the absence be treated as excused. Job hunting and attendance in other classes are, in principle, not accepted.

Grading Method Attendance is required. Grades will be determined based on the average results of the short quizzes or short reports assigned in each class session, together with an overall evaluation. In principle, each short quiz or short report must be completed and submitted within one hour after the end of the lecture.
