Please be advised that when students reach a certain age (i.e. mid-teens and older), their exams become very content-based and, therefore, revision lessons need to be quite intense in order to be effective. The odd ‘fun’ lesson here and there containing learning games and competitive quizzes can offer a nice break from the intensity of completing whole papers. However, ‘fun’ lessons like these tend to be less efficient at embedding high-demand content than, say, a lesson in which students complete a 40-minute assessment filled with past-paper questions.
