This system is very helpful and easy, each lesson is about 20 minutes, which is about as long as most people can concentrate before their mind begin to wander a bit. Lessons start out with the most basic conversations, and the conversations get a bit more complex as they go on. It is very helpful in helping the student make the transition from a language sounding like jumbled mess to being able to pick out words. No straight vocabulary is presented, it is always within the conversational framework. I do wish there was written guides for each lesson reviewing the words and phrases actually used. Well worth the money.
