Assessment Methods
The exam includes a written test and an oral exam with sufficiency fixed at 18/30.
Written examination:
- part 1: 25/30 multiple choice questions (1/3 of mark)
- part 2: 5 written exercices (2/3 of mark)
Oral examination:
- theoretical questions and practical queries.
The final mark results from the weighted average between the written mark and the oral mark.
