Say there are A, B, C, D, E, F, G, H, .......... courses and a student X has to be enrolled in courses A, E and G without giving him enrollment keys (enrollment keys can be circulated among friends). From the roles tool currently it does not seem to be possible to assign role to user X in courses A, E and G simultaneously. One has to assign role to the user as student in all the three courses separately. It is quite time consuming especially if this needs to be done for many courses individually. Am I missing something?
From what I've gathered, those three courses would have to be in their own unique category. Then you would assign those students the role of student at the category level, and they would then automatically have access to only those 3 courses. I've not tried this, though.
