A subject or course is used to group your classes, tasks and exams together. The subject consists of a name and color, in order to make the subject distinguishable across the application.
If you are only taking the subject for a short period of time, such as over a single term or year, you may assign the subject a year or term. Any classes assigned to this subject will only repeat during the year or term specified by the subject, unless assigned a term beneath the subject’s year or start/end dates.
