This system of learning a language is very successful. It really works. Just do as the guide to lessons tells you and you will succeed in learning a new language. I did German at school, I am half German and only used German at summer times as a kid when we would visit Grandma (Omi) in Germany. I could understand and converse a lot less then. Now, due to the Pimsleur method of learning I have a confidence in really understanding and holding a conversation in German. Very, very highly recommended for all that wish to learn any language in the series of languages.
