Hi, I'm trying to figure out if I can put a bunch of courses in a single learning plan, but am not sure about the following.

If a Learning Plan has four mapped courses, on a 12 month renewal interval, and 3 of them are completed in January, and one of them in June, when will the Learning Plan come up for renewal?
