Hello.I have studied that school for 6 months.The class is quit different depend on teacher.Some teachers were very interesting.But some were boring.But if you complain to the cordinators,they can help you very well. I think in spring there are about 11people ,Japanese are 30% in the class.If your level is very high,Japanese are about 15%.I guess...But in summer there are over half Japanese.Last summer I was.I’m sorry I’ve never joined the school activities.I think it is more expensive than usual.If you need more information,do not hesitate to ask me.
