| Normally, the evaluation would have been based on written and oral exams. | The evaluation will be solely based on oral exams, which can involve the assignment of written exercises. |
| | |
| Due to the covid-19 countermeasures, for the current period, the evaluation will be solely based on oral exams. As an alternative to the assignment of exercises during the oral exam, students can develop a small project before the exam (contact the teacher if interested). | |
