Retired engineer (X, Sup'Aero), I offer Mathematics and Physics/Chemistry courses to high school students from Yvelines or Hauts-de-Seine in the scientific sector (1ère or Terminale, S or ES), also supporting students in preparatory classes wishing to take an entrance exam for a school (engineering, business or physiotherapy) or adults in professional retraining via a scientific university course. Throughout my career, I have very often had the opportunity to share my knowledge by providing courses related to my professions to students (Schools, Universities) or professionals in continuing education; since my retirement, I have given private lessons to several students, helping them to graduate and also giving them back the taste for science, which I consider necessary to pursue higher scientific studies. Seeing my role as complementary to that of school teachers, I seek to teach a methodology as much as to find solutions, by consolidating the foundations of scientific knowledge acquired during previous years and by arousing the curiosity of students by sharing my knowledge. feedback as an engineer. My area of intervention: 78/92: Versailles and nearby surroundings
