Course Numbering（K-Number）

　Beginning in the 2022 academic year, Keio University will be introducing a course numbering system (K-Number) which shall take effect with regard to all courses to indicate the course's level, academic field, and class format.
　The K-Number system will allow students to search for courses in academic fields of interest and learn based on a systematically organized academic plan.
　For courses which are offered jointly between multiple faculties or undergraduate and graduate levels, a separate number will be assigned for each faculty/graduate school respectively.
Please check the K-Number for each class in the Syllabus and Timetable Web Search.
