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.
* For synchronous interactive classes, logging in 30 minutes or more late and/or leaving 30 minutes or more early will be treated as an absence (attendance will be verified using the Teams participation log, etc.).

Policy on Absences:
* Six or more unexcused absences will result in a failing grade.
* If you must be absent for an unavoidable reason (*see Note 1*), you must notify the course coordinator by email as soon as possible, either before or after the class. You must also submit (later is acceptable) a photo of documentation that can verify the reason for your absence by email. Only when all procedures are completed will the absence be treated as excused.

*Note 1: Unavoidable reasons include illness/injury/accident, bereavement, participation in events hosted or officially approved by the university, activities of university-recognized student organizations, and disaster-related volunteer activities. Job hunting and attendance in other classes are, in principle, not accepted.
*Note 2: Examples of dated documentation include: a receipt from a medical institution, a public-transport delay certificate, a postcard notice of a wake/funeral, or a certificate bearing the seal/signature of a club captain or faculty advisor.

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