One of the challenges that some students with three-year undergraduate degrees have is that some masters degrees require four years of undergraduate study. ESCEM, the AACSB-accredited 'Grande Ecole' business school in Poitier and Tours, has a solution. It has a one-year BA in international business for people who have already completed some years of undergraduate study, with at least one year in a business-related area.
