Odd and bi-weekly courses can be achieved through the settings of "Basic Information - Lesson Information".

For example, this week there will be 2 music sections and 3 art sections, and next week there will be 3 music sections and 2 art sections. Then you can set up a music class with 2 weekly class hours; an art class with 2 weekly class hours; and then set up a separate "single music/double art" course with 1 weekly class hour and the teacher is "music teacher + art teacher", so it is arranged In the class schedule, there will be a "single music/double art" course, that is, music is taught in one week and art is taught in two weeks. In the same way, if more than two courses are taught in rotation, they can be set as "Course A/Course B/Course C", and the teachers can be set as "Teacher A+Teacher B+Teacher C".
