I am a student in a preparatory class for Grandes Ecoles (CPGE) integrated into EPITA (computer engineering school) who has been giving support courses for 2 years to students in an association. Going through the preparatory course allowed me to acquire effective working methods, where the watchword is rigor and curiosity. It is also important to adapt your course to the student's profile to put them in the best possible position so that they can best exploit their potential. I have given lessons both individually and in small groups. My students have always seen an improvement in their grades and a better understanding of topics after my lessons. MY MORE: 1) Patience, pedagogy and good humor 2) Free follow-up by telephone, email and instant messaging to answer my students' questions, video explanations if necessary. 3) Help with orientation and choice of specialties, connection with former students and professionals. 4) Coaching (stress and confidence management during checks, advice on working methods, special training for checks / white baccalaureate) Together, we will review the concepts that pose problems and transform them into strengths, so that students approach questions in class with confidence and serenity. We will use examples common to everyone to represent mathematical concepts. The course of the course will be based on the needs of the student. Firstly, we will review our knowledge and then we will practice knowing how to do typical exercises.
