[Orgmode] Organizing a students live

[Thomas Bach]

Hello,

I came to org-mode through the Tutorial of John Wiegley[1] and I'm
loving it! A great thanks to all of you who are working on this awesome
piece of code.

Actually I'm trying to integrate all my university stuff into my
org-files and I'm a bit stuck.
All my university stuff means: there is a certain date when a semester
starts and another one when it ends.
During that time I have to go to a couple of classes which usually have
"homeworks" related to them. In addition there are vacations (hooray!)
and holidays.
At the end of a semester some examens and theses need to be written.

How would you guys express all this in an org-file?

I solved the start, end and vacation thing like this:
------------------------------------------------------------
** APPT segundo cuatrimestre
   SCHEDULED: <2010-02-08 Mon>
*** vacaciones
    SCHEDULED: <2010-03-15 Mon>--<2010-03-19 Fri>
*** finaliza segundo cuatrimestre
    DEADLINE: <2010-06-04 Fri>
------------------------------------------------------------

Examens are APPTs too. Well, it works, but to me it doesn't seem to be
the proper way to do all this.
Espacially I have no idea how to integrate the classes and their
homeworks now.

Greets,
        Thomas.
