For parents and carers
Everything on these revision pages is free and works without an account.
The most useful thing to find out is the exam board and specification code for each subject. The school can tell you, and it is usually printed on mock papers. With it, the course pages show exactly which topics are in the exams.
Short, regular practice works better than long cramming sessions. The study guides explain active recall and spaced repetition in plain language, and the timetable page puts each exam date into Exam Countdown.
If exams are causing a lot of worry, talk to the school. Young people can also contact Childline, free and confidential, on 0800 1111.
