The preparatory years are organised in a number of programmes for specific audiences, in particular to grant access to certain masters.
These studies entitle to a certificate.
The students who want to benefit from “bridges” which give access to the second cycle of studies at the university, can gain information at the secretary's office of the faculty, in case they can't find below the preparatory year for the field they're interested in. The may then consult the pages concerning passerelles ( bridges).
