The compulsory or optional final written examinations are those specified in the regulations currently in force at ISEC.

The examinations are multiple-choice examinations, requiring students to answer 10 questions/items selected from 12 questions. Correct answers (from five possible options) are awarded 2 points, while incorrect answers are awarded −0.5 points.

During examinations, the use of any electronic device or any reference material is prohibited, with the sole exception of one A4 sheet containing material of the student's choice. The use of a calculator without communication capabilities is permitted.

With reference to point 11 of Article 31 of the Academic Regulations for IPC first-cycle study programmes, only the material mentioned in the previous paragraph, together with a reasonable amount of writing materials, may be brought into the examination room. In particular, backpacks, academic folders, handbags, etc. may not be brought into the room, as they may facilitate academic misconduct.

The mere possession of any electronic device other than the calculator will be considered academic misconduct, resulting in the cancellation of the examination and the filing of a disciplinary report. “Possession” is understood to mean merely having the possibility of accessing such devices during the examination, for example, by having them in one's pockets.
