The lessons are accessible through the below menu.
If you’re new here then of course you should start with lesson 1. The following lessons are eached based on the former lesson. It therefore makes sense to work yourself through one unit after another.
At the end of each lesson there is a small vocabulary list which you should learn in order to be able passing the exercises.
If you prefer printed paper it’s of course possible to print out each unit.
Soon there will be also a book version in English available. As soon as available it will be announced here.
