26-year-old student in MA2 in aeronautical engineering offers private lessons in mathematics and science for high school or higher students who need help in one of these subjects. Very often in contact with young people in my activity as a mini-business consultant, my goal is to make the subjects I teach lively and interesting. I work a lot on building the students' confidence in their own abilities and on practical sessions where I show how to apply the theory seen in class. I also teach my students to make concise summaries of their courses in order to be able to study it effectively by putting the right priorities by structuring the material which at first glance may seem complex.
