The purpose of these courses, is first of all to help and learn a new thing to the person, but also to learn and adapt to your world. I am still a student, I speak perfect French, English and Arabic (given it's my native language), I'm doing quite well in Italian. This course can last a long time. The time you understand the subject. Or as also it can be very brief (for example as a rehearsal or other) I am really a very motivated person, and I am ready to move. Part to teach others and also to pay for my studies.
