Hello, I propose courses of support in mathematics, for secondary and higher. I propose a personalized help to allow the understanding, and the preparation with the interrogations and exams. I am currently a postdoc at UCL, holds a doctorate in mathematics since 2017 (Ecole Normale Supérieure, Paris), I give courses at the university or high school since 2014, and level private lessons secondary school or more since 2009 (beginning of my higher education). I am used to seeing varied profiles in private lessons, from pupils with severe difficulties like discalculy to students with great facilities.
