Hmmm well, looking at the playmyace posts, Hong Kong was running a Chinese class and Pip and our last Seras were running a survival course and Raphael was teaching gym. Everyone else seems to have dropped or been reset.

Seifer could always teach some things. He does know more than how to stab things, surprising as it is someone should blackmail him into teaching ballroom dancing. He's also going to see about getting someone (possibly Ukraine? Idk) to set up a first aid class so that could probably run out of the school too.

Aaaand aside from that I think part of Germany's introduction to Discedo course takes place in the high school so that could always just sort of, be added in for organization's sake fff.
