@Yellow I think that it's a great idea! I think that having two classes a day will give the teachers more to do as well. It could be more of an option class though? So the first of the day is chosen by the GMs but the second one of the day is chosen by each individual. They could choose tue top 4 that they would eat to study and from that, providing that there is enough space per class, they could participate in one of the classes.
I know that it is fairly similar to what is in place already for the first class. But just an idea
