Hans

きちんとした文章になおしてアウトプットさせてくれるので
スピーキングの力がつくと思います。

カランで受講。発音がとても明瞭で聞きやすい。高速で読んでくれるのでリピートしやすい（記憶を保っている間に口から出せるので）。つっかえた時も、その単語のみ言い直させるのではなく、センテンスで言い直しさせられるところも良かった。カランはこうでなくちゃというレッスン。

He's good teacher for Callan method.

He speaks clearly and speed is nicely fast. I like the speed.

Hey teacher Hans, thank you very much for helping me alll the time.
I can't thank you enough.
Recently, I have been learning English every day all day, I think I have improved a lot and I have learnt quite a lot, that's for sure, furthermore, this week I speak a little fluently than last week, that's because you helped, I'll stick the good work.
Thank you for the help again, excellent teacher.
Best to you!
John.

It is a very polite lesson. Thank you.
