Correct. Lot’s of official youtube playlists and links to the various institution’s own pages for them. I’ve tried to keep it so most of the material in my own collection is book based rather than original coursework. Otherwise, whether or not the assignments and assessments can actually be found is kind of a crapshoot. It seems like a lot of institutions pulled back on their coursework sometime over the pandemic, presumably reassessing their value given what appeared to be a long term shift to virtual learning. I’d like to get organized about what resources are actually available and am currently looking for community feedback on how to do that in the most effective way.
