Well as the title says, it will work only if you work it. This does not mean swotting day in day out. The way I do it: I lay down on my settee and listen. I'm a slow learner and I some times can't make out what has been said. But I persevere and eventually get it.
The package comes in eight lessons, I am now on number five. I am having difficulty understanding what is being said on this lesson.
But I know if I just keep going, that is, lying on the couch and listenening.It will finally be understood as in the previous four lessons.
I gave this three stars not for the whole package,but for the lessons that I have gone through. I will probably give it the whole five stars, when I complete the eights lessons. And that depends on me. I know it will work only if I work it. marsalarma ( Goodbye)
