DS is pretty average academically but would like to get 6s and some 7s in his GCSES. He had been revising most evenings but I’m suddenly aware that it’s not long now until the exams start. He’s been working through topics for each subject quite thoroughly but not even covered a quarter of the syllabus yet and I’m worried he’s running out of time. I don’t want to stress him out and could really with some advice on the best approach.
