If the teachers come in prepared, enthusiastic, they've got a list of activities that corresponds to what you need and where you want to go. But sometimes, the teacher will just turn up and expect that being a native language is sufficient to be to do the whole hour without preparation. In that case, then you've got to take real control and step up and take that responsibility. And I think personally, most if the teacher's good, they'll be happy that you're doing this,. That you're initiative and helping them get give you more value. Absolutely.
