Yan, Engineer, and trainer. I offer support courses in mathematics from primary and from ce1 to 3iem and help with homework in all subjects at college level. I adapt to my student. There are no bad questions or fears to be had. I will be a real support to achieve the goal we will set together, a good notebook and a successful patent. We will overcome fears and apprehensions, to reach the desired level together. I have a good experience as an internal trainer in a company resulting from my experience in the engineering profession for 20 years. I return to my first vocation, teacher.
