With Pimsleur Language Programs you don't just study a language, you learn it -- the same way you mastered English! And because the technique relies on interactive spoken language training, the Pimsleur Language Programs are totally audio -- no book is needed!
The Pimsleur programs provide a method of self-practice with an expert teacher and native speakers in lessons specially designed to work with the way the mind naturally acquires language information. The various components of language -- vocabulary, pronunciation and grammar -- are all learned together without rote memorization and drills.
Series 1,2 and 3 are here with some "extras".
