For more than 60 years, Assimil has been a leader in language learning materials based on a simple principle of intuitive assimilation, or natural learning. The method comprises two phases: a passive phase, where the student simply listens, reads and repeats for the first few weeks; and the active phase, where the student begins to communicate spontaneously using the naturally acquired language from the first phase. The method is simple, gimmick-free and has already helped millions to learn a foreign language. The book and set of 4 CDs or audio-cassettes are available separately or together in a multimedia pack. Total running time for the audio material is 2 hours 50 minutes.
