Second year student in a dual economic and cultural program at La Sorbonne Paris1, I validated my first year easily and obtained my Economic and Social Baccalaureate with honors with grades of 18, 19 and 17 in the subjects of SES, mathematics and history. My goal is to get this same mention to any high school student in this same sector or S stream in history and mathematics (my first year at university having allowed me to catch up with the scientific program). I can also give these courses to any schoolboy or anyone wishing to learn his notions knowing that I have a university level in the subjects of economics and mathematics.
