Someone emailed this to my friend's Biology 152 lecture.

Ah ok, thanks. Makes sense.
I guess we have a similar service, we just don't put that much emphasis on it. The course codes here look something like MAT-10406. The last 2 digits stand for the amount of credits, the first digit indicates the year or difficulty. That code would be an introduction to statistics. MAT-20406 is a direct follow-up. We don't have much of those at all. I don't think I've done one. We usually have courses that focus on 1 topic, so there's not much to follow up to.
