I´m Professor Prima, a native German teacher. The most effective way of learning a language is the natural way. Just like a baby learns a language. A five year old kid can speak, but has no idea what a dative or an accusative case is. A kid has heard and repeated the words and sentences several times without studying grammar.

By watching Professor Prima´s animations, you learn by seeing, hearing and repeating. The natural way. The time for grammar and complex theories comes later. First you need to learn the language just like a baby learns, the natural way by seeing, hearing and repeating:)
