This course is aimed at students wishing to strengthen their skills in mathematics, computer science and engineering sciences, three complementary disciplines for developing logic, rigor and analytical skills. The objective is to support each student according to their level and needs: 🔹 In mathematics: understand concepts, solve various exercises and prepare effectively for exams. 🔹 In IT: learn programming (Python, Scratch, C++...), algorithmic logic and the use of digital tools. 🔹 In engineering sciences: discover the principles of modeling, mechanics, and electronics. Each session is structured to make the student independent, confident and motivated, thanks to clear teaching methods adapted to their pace.
