Hi.

I think you may be able to master 3 minutes speech in Japanese/German, or learn lyrics of one Japanese/German song, in 1 month.

I mean that it is possible to learn a certain amount of specific context, in 1 month.

If you want to do it, an effective tutoring system is necessary, in order to save time.

And of course, you have to do nothing but study the language.
