Wrt the original topic, I'm sorry for not giving any feedback anymore, but I did not have an time whatsoever for this issue over the last few weeks.
Special thanks to tamasd for the pointer to flash card progras like pauker and jmemorize, I'll have to check those out. I'm not after the content of the curriclum, only the schedule, but maybe one could use the flash card apps. But it's a nice idea for a workaround.
OTOH, I don't think Rainlendar supports irregular repeat patterns like the ones I mentioned.
