"They are optional to go to or participate in and teachers put up a notice in advance what their class is going to cover, so you can know if you want to go or not. That makes them more interesting to go to than a regular school, aside from the subjects taught not being anything like what I had to learn at my school back home. And the classes aren't held regularly, more on the whim of the teacher than anything else." So not really like an ordinary school at all.
