I'd like to put my schedule into org-mode, so that I can see my classes in the agenda. I have different classes, repeated every week, all of them taking 90 minutes. I was thinking about something like this:
* My schedule ** Differential equations <2012-10-04 Thu 11:45 +1w>--<2012-10-04 Thu 13:15 +1w>
However, there are two problems: I can see only the next instance in the agenda, and I can't see the ending time. Any ideas?
