Every teaching unit consists of 45 minutes and takes place where you like it. I recommend to book a 90min- appointment of two teaching units, because a single unit is often too short to successfully engage in learning german. To my opinion, the learning success increases the smaller the learning group is, because the teacher can focus on the individual needs from each student and therefore no one gets "lost".  I do not recommend more than 10 persons per lerning group, as the lerning success of each one of them cannot be guaranteed. Private and Business courses start the same: first, the everyday life language has to be learned. Starting from Level A2-B1, you can learn business related. Still, the everyday life language remains a part of each course.

All courses consist of the following skills: reading, writing, Llstening, speaking, role play, engage in dialoges, discuss pictures, learn specific vocabulary for specific situations, train vocabulary.
