As a mathematics teacher (CAPES), currently preparing for the agrégation, I offer personalized support in mathematics for middle school, high school and university students (BTS). My background is atypical: I have worked for more than 25 years in the private sector in general management internationally (Europe, Africa), which allows me to bring a concrete and applied approach to mathematics. I primarily offer online lessons, which allows me to support students throughout France. I also offer in-person lessons at students' homes in the region (subject to availability). My services: refresher courses, preparation for brevet/baccalaureate and post-baccalaureate exams, applied mathematics (BTS, management, commerce), assistance to students in difficulty. My method: simple and progressive explanations, a practical approach (linking to real-world situations and businesses), and personalized follow-up. Objective: to give you confidence and help you progress quickly. Online courses offer great flexibility, save time, and are incomparably (or even superior) to in-person classes. I also teach in English.
