This online math course is designed for middle and high school students following the French curriculum. The sessions are tailored to each student's level, objectives, and specific challenges to ensure effective and confident progress. The lessons allow students to review key concepts from the curriculum, work through exercises, prepare for tests, the Brevet or Baccalaureate exams, and improve their study methods. My goal is to help students understand mathematics in a simple and progressive way, with clear explanations and personalized support. Thanks to my training in Mathematical Modeling and Scientific Computing at an engineering school, I offer a rigorous and pedagogical approach to help students develop their skills and gain autonomy.
