Online study is best done in learning communities that are not too large.  This ensures positive discussion dynamics and the inclusion of all participants.  Given the high number of students in some modules, you will see in that in All Courses we have divided some of these modules into Cohort A and Cohort B.  You will be enrolled only in one of the two cohorts, and will not be able to access the other to avoid confusion.  Both cohorts will follow exactly the same programme of study under the same tutor.
