EnTren (Education - Languages)

EnTren is a trainer of perception of English (or another) speech. More precisely it's a step-by-step player+ Means of check and compulsion of understanding (fast - input) + Statistics and estimations. So, it is not simple, but very simple. But it works! - My daughter (for whom it's made) had sited before it already 40 hours, whereas with other systems she had worked for 15 minutes a maximum!
