When do lessons unlock?
Why you can see a module but not open it yet.
Learners
The whole curriculum is visible from the day you enrol, including the weeks that have not opened. You can see what is coming and plan around it.
Lessons inside a module open in the week the mentor set for it. This is deliberate: a cohort works because everybody is roughly in the same place at the same time, and the discussion falls apart if half the group has finished.
Once a lesson is open it stays open. Nothing expires while your enrolment is active.
