Most courses have a two week instructional period, with an extra week of access at the end which allows time for review. The course requirements must be completed within the first two weeks. There are a few exceptions* to this, but a large majority of courses are two weeks. If you are uncertain when the course will end, refer to the initial welcome announcement you received at the beginning of the course.
* Data Analytics courses (SHA570 series), Nutrition and Healthy Living courses (DNS600 series), or those beginning with course codes in an 800 series, HADM or NCCY do not follow this two-week rule.
