I read a lot about this application. And I am wondering? Does anyone really learned a new language using such software? Is it worth to try it or better go to more traditional practices (realtime classes etc)? It would be nice to learn a new language with your own pace and at your own time but will it work at last? Is it worth to spend money and time using this application or it is difficult to learn a new language depending only on this as a basic tutor?
