Currently studying in DUT in Business Administration and Administration in second year, I master economics, mathematics, English and management sciences. I propose to students ranging from 6th to 1st classes in English (all sectors combined), mathematics (ES and STMG) and SES (sociology, economics and perspectives). This allows students to improve their level in these areas. The course takes place in several stages: - Resumption of the student's course on the theme and explanations - Application with corrected exercises (level of difficulty crescendo) and possibly controls already had by the student. - Exercises to be done for the session after
