Graduated from a BAC + 5 in Mathematics, I first became an engineer in the world of space and in the world of aeronautics. After a few years in the industry, I came back to my first love of mathematics by passing the teacher contest. I am now a certified math teacher in high school and high school. My class always starts with 2 minutes of relaxation, which then improves concentration. My goal is, on the one hand, to provide keys for students to learn to learn, so that they discover the methods of understanding and revision that suit them. For that I help myself in other multiple intelligences and discovers on memory in neuroscience. Depending on the students, we will be able to put places of revision sheets, mental maps, method sheets, etc. On the other hand, my goal for each chapter is: - to explain the course with other words and pictures so that it is well understood - to take a step back on each exercise, by analyzing the statement, by breaking down the steps necessary for the resolution - to explain the methods of solving the typical exercises of the chapter
