Master student in thermal engineering and energy offers individual private lessons for students in primary, middle and high school. My goal is to motivate and give the student the desire to learn, while strengthening his level in Mathematics and / or Physics. My method is first to re-explain the parts he did not understand the course, then make direct applications to better assimilate the course and finally exercises that will not only strengthen its level, but also that will arouse his curiosity and his desire to know more.
