A master is a two-year (4 semesters) course, accessible to students who have completed a bachelor (or equivalent). The admission criterion for master 2 (2nd year) is a master 1 or equivalent qualification. Your previous studies must be relevant to the master's programme you wish to take.
Engineering students who want to go onto doctoral research can take a research master 2 during the last year of engineering school.
A master can also be taken over one or two years as part of a continuing professional developmentprogram.
