Teaching with Moodle

The metacourse would allow you to keep only one set (copy) of the materials. You set up two courses, one for undergrads and another for grads, each with a different price, then make a metacourse with those two courses as its children. In each of the children courses, you place a link to the metacourse as the place where working materials etc are. The side benefit could be that you can also provide stuff which is specific for each group without other group knowing about it.

Note that this question is more an enrollment issue than a teaching strategy, so it really belongs in the enrollment forum, although I can see how it could be considered a teaching strategy issue as well.
