This course is intended for high school students who wish to progress or better understand the SES or to people who wish to understand the basics of economics and sociology. I'm just graduating from a business school (economic option), and economics is a subject that interests me a lot. This is a subject that, if you are interested in it, can understand a lot of things about the news. I propose to reread the student's courses with him or other courses if his are not complete, to propose exercises, and to review the method of study of document and dissertation. Indeed, debating a course in economics or simply speaking about it is one of the best ways to remember it and understand it in depth.
