If your DS is not enjoying and learning in the club, I would stop it. Is it possible for you to get a credit for what u have paid and or transfer him to another activity that interest him? If not, I will just let him finish this semester and not continue.

I once signed up DS for Go with a private teacher as he wanted to learn the game. It didn't work out because the teacher was rather strict (the game is strict too). Hands at the side..... no touching your own pieces..... no questioning during the teaching session (only the teacher was allowed to "set" the pace and the strategy). DS was frustrated because he could "foresee" the next pattern / formation and he has lots of questions to ask but was told that those would be covered in later lessons! Luckily the fees were paid by session, so I stopped after 3 sessions.
