Course addressed to students between the 3rd and the first two years of university through high school. With the experience of ten students in private lessons and teaching at the Faculty of Orsay, I offer my help to overcome your difficulties in mathematics! As my description specifies, my method is very simple: learn to understand! This is how we spend less time learning because we anticipate the important concepts to remember as well as the ways of doing mathematics well! My methodology will obviously vary depending on the student to achieve as quickly as possible to fill his gaps and progress independently in the future! And yes the endless course - exercises does not work with everyone, it is not useful to overload yourself it is better to understand rather than to learn by rote in mathematics as I said previously. Hope to make you realize that math is not as nightmarish as it can seem!
