The thing is, if she doesn't revise for her Y10 exams, or mocks, there will be so much to revise for the first time when it's the real thing it will be completely overwhelming.
My son is very bright but has no idea how to organise himself, estimate how long something might take, or accurately gauge what 'enough' revision is. So I have made it non negotiable, we did a revision timetable table together and I help him when needed, or insist he gets on with it when the task is independent.
He doesn't push back on this and we don't have arguments about it, so it works for us. What you decide to do very much depends on your daughter and her reactions..
There are also loads of ways to revise. Flash cards and past papers don't appeal to my son so we found other ways (Seneca interactive revision, very satisfying to tick off sections - YouTube videos and looking at past papers and the mark scheme rather than endlessly doing them himself). These methods worked for his Y10 exams and mocks, we shall see the real results in august. But doing it a bit at a time for each set of school assessments will definitely help in a years time, if you can make it happen without conflict.
