Réponse : en espaçant les examens.

C’est ce qui ressort de cette étude sur données américaines de Ian Fillmore et Devin G. Pope, qui s’intéresse au lien entre fatigue cognitive et performance : les étudiants qui passent deux examens à 10 jours d’intervalle ont 8% de chance en plus de les valider que ceux qui les passent à une journée d’intervalle. Je garde cette idée en tête pour l’organisation des examens de fin d’année.

Résumé : In many education and work environments, economic agents must perform several mental tasks in a short period of time. As with physical fatigue, it is likely that cognitive fatigue can occur and affect performance if a series of mental tasks are scheduled close together. In this paper, we identify the impact of time between cognitive tasks on performance in a particular context: the taking of Advanced Placement (AP) exams by high-school students. We exploit the fact that AP exam dates change from year to year, so that students who take two subject exams in one year may have a different number of days between the exams than students who take the same two exams in a different year. We find strong evidence that a shorter amount of time between exams is associated with lower scores, particularly on the second exam. Our estimates suggest that students who take exams with 10 days of separation are 8% more likely to pass both exams than students who take the same two exams with only 1 day of separation.
