English is a simple language. To be able to give a quality course, I rely on the student's knowledge to know where he is in his apprenticeship. Once the weaknesses are noticed, I will make them work and understand. The work of understanding is not always easy, that's why I would help it with my own knowledge. This is a work on the long term child, indeed to assimilate things and to understand them can be difficult, that is why we must not give up.
