Other information
Attendance is strongly recommended
Learning verification modality
Knowledge will be assessed through a written test administered via the Libreol platform, supplemented by an oral examination.
The written test consists of 33 questions with closed-ended responses, open-ended responses, and image analysis tasks.
The examination procedures are described in detail in a file available on Unistudium and uploaded annually approximately one month before the beginning of classes.
The file is presented during the first lecture and explained in detail. It describes and details the procedures for the written test and the conditions for taking the oral examination.
