Student in the preparatory class at the grandes écoles de commerce I can share an efficient work technique and a more effective learning technique that will not overload the student. The courses will be related to support or to the deepening of the courses seen in the schooling of the pupil. The goal is to set with him his expectations and his objectives and then set up the most productive technique to get there. This will provide new knowledge and a method of work that will save a lot of free time and allow the student to better balance his work and his outdoor activities.
