Assessment methods

The oral examination consists of an interview between the candidate and the teachers. During the oral examination the candidate may also be asked to solve "think as a scientist" or to try to approach an experimental problem with the right scientific plan. The duration of the interview is about 40 minutes, the number of questions is generally 4.
