English
I offer the following for English learners from level A1 to level C2:
business English (these classes can cover a variety of topics and content connected to your job or application efforts, e.g. )
pure grammar (which makes sense to introduce you to certain grammatical structures but then should be combined with practice)
mixed content like grammar exercises, spoken practice, conversation, discussions, presentations etc.
pure conversation with correction and feedback
To find out your language level, take a language test like this:
