it seems that the only real change may be that there is no more counsel slips (right?) and the every part is a presentation/bible study (like the sister's parts used to be). I also notice that the last presentation can be assigned to an elder from time to time.
For those that didn't join the school I wonder if now there is no joining so that everyone in the KH is fair game to get a request to do a presentation. That could up the nerves of a few people I know that weren't on the school.
