Noah is an average student. He doesn't really like math, at least he prefers playing soccer with his friends. The worst part is, he changed schools this year, and his difficulties have increased tenfold. Noah wants to become an engineer, and his math grades don't reassure him. Noah's parents are also worried about his grades. They decide to contact me. During our first session, Noah seemed desperate to me! So I'm thinking, what if we start from Noah's domain of definition, that is, football. We can pass and dribble, move up the stadium, vary speeds depending on Noah's heart rate, make combinations to increase our probability of leading the perfect offensive: review coordinates, vectors, parameters, remarkable identities, trigonometry, functions, limits, directions of variations, derivatives, asymptotes, extrema, probabilities and even differential equations of the field in order to prepare the unstoppable assault. After a month, Noah scored 18/20 on his test, much better than the 8/20 he scored on his previous test. Noah's acceleration was almost perfect! Hi, I'm Fabien! The one who hatches Champions! Because your hobbies are not trivial to me, and today's shortcomings can be corrected. I'll give you simple tips and tools, mnemonic methods, and above all, I'll give you back the desire to become a Champion! So, are you ready to become an expert in math?
