Frequently Asked Questions
Our language courses were developed according to the "Birkenbihl method". Vera F. Birkenbihl was a bestselling author and management trainer who devoted her life to perpetual learning. "Brain-friendly learning" was a special concern of hers and so she developed her own method for language learning, the so-called "Birkenbihl method".
This consisted of translating a foreign-language text into one's mother tongue by "decoding" the text (word-for-word translation). We have further developed this method and created software that makes it possible to use the "Birkenbihl Method" as an app for computers, smartphones and tablets.
Our basic courses are aimed at beginners and returnees. You do not need any previous knowledge and thus learn to communicate optimally in everyday life.
Our advanced courses expand your basic vocabulary, allowing you to express yourself in an even better and more complex way. This course is ideal in combination with our basic course, but of course you can also start here if you already have the necessary previous knowledge.
We currently offer courses in German, Spanish, Italian, French and Russian for English native speakers.
Courses for your native language can be found here:
