Mathematics and physics are the cornerstones of understanding the world. As a Master's student in Mathematics and Physics (AMIS) at Paris-Saclay University, I teach a rigorous method for transforming complex concepts into simple and intuitive solutions. I designed this course as a practical and structured learning tool for secondary and higher education students. You will learn to master the tools of analysis, algebra, and mechanics, while developing practical problem-solving skills. We will work on clarity of reasoning, precision of writing, and the direct application of formulas through progressive exercises to ensure your success in exams and competitions.
