The best way to learn to learn is still to learn. Associate professor in IS, PhD student and engineer in engineering sciences and modeling gives private lessons in mathematics, physics-chemistry and engineering sciences with a solid experience of 4 years as a private teacher and embedded systems engineer at my account on the Upwork platform. * I strive to identify the gaps and learning difficulties of learners by using the active method of simplicity that makes elegance. * I adapt so that the learner regains self-confidence, grasp the fundamental concepts and acquire an autonomous approach in solving problems. * Guide, support and follow the learner. * Report and evaluation. I am also available to give private lessons to young students (CPGE-FS- FST- ENSA-ENA). Some examples - Testimonial - - TC BIOF student, mathematics. Graduation from 8.5 to 17/20 in the average of the homework for the 1st semester. - Student of BAC SMB, engineering sciences. Passage from 1.5 to 14 of average of BAC Normal --- Catching up. NB: The recommended duration of the sessions for optimal progress is 2 hours.
