Assessement methods and criteria
The final examination consists in a written exam and an oral exam.
During the written exam, the student must solve some exercises, with the aim of assessing the student's ability to solve problems. In the oral exam, the student will be required to illustrate results presented during the course and will be required to solve problems.
