It's a very well thought out progression through the language. And starts in immediately with practically applicable language with the rules of grammar sprinkled in here and there. Enough so that you actually learn the mechanics of the language but not so much per lesson that it becomes overwhelming or dull. All in all it's a very very good course and I'm very happy with it.
