Could I ask you how you or your DCs revise(d)? DS just looks at the textbook he uses in lessons. No commonly referred methods such as organising notes, flashcards, writing down repetitively etc are going to be happening. Sometimes I wonder if I should encourage him to try and practise different revision techniques as I am not sure just staring at the textbook would be enough for GCSEs, A-levels and beyond... How about your DCs or you when you were a student? If you or your CDs were like him, you/your DCs did fine or struggled once things got trickier?
