Book & CD. All Assimil courses are based on intuitive assimilations®, an original principle that is simple yet highly effective. Assimil has taken this natural process, through which you learned to speak your own language, and adapted it to their book and audio courses. Working progressively, with natural, lively dialogues, simple text notes and exercises, you will progress steadily to a level where you are able to converse in everyday situations. The first part of the course is the passive phase: you immerse yourself in the language by reading and repeating each lesson. During the second, the active phase, you use the structures and reflexes you have already absorbed while continuing to advance and learn. In just a few months, you will be able to speak French easily, fluently and naturally.
