Exam rules (only in person for the summer session in 2022):
- The exam consists of a written test (2h30m, with Moodle) and a compulsory oral test.
The oral test takes place on the same day or on the next day(s) if there are many students (the schedule will be communicated on Teams and Delphi).
- To access the oral, a grade of at least 18/30 must be obtained on the written test. The exam is passed if the final mark is at least 18/30.
- The written test and the oral test must take place in the same call.
- Under penalty of exclusion, during written tests the use of electronic devices and applications except those required (MS Teams and possibly a web browser to access to
the Moodle quiz) is not allowed. It is not possible to use books, notes and calculators.
A simulation of the written test is available on the site.
