Graduate engineer in Nuclear Physics and Micro-Electronics, I teach Physics and Mathematics courses at Middle School (3rd and 4th) and High School level (S and ES sectors). With several years of experience, I have followed middle and high school students from different sectors (particularly S, ES in high school) with very satisfactory results in the short and medium term. Being currently abroad, I teach lessons via webcam. The modalities will be discussed and then fixed by mutual agreement (course material to be used, approach, methodology, course format)
