Good, right, but not easy for beginners. From what I saw, some would get bored soon on #1 and #2, most would give up after several months practice when they found they didn't know how to do #3, only few would stay and would still have to do that after some years' practice. Consequently, it's hard for the dojo to survive.
No time to get bored, it's only a two month class.
Why would people get bored? Why would they find they don't know how to do? Sounds like a class with no teacher.
