Having a Year 11 taking GCSEs at the moment I would stick with the flexible ‘hour’ a day scenario, as there’s a lot of subjects at GCSE and it’s hard to give them equal attention.
Realistically she can’t do an hour a day if she has lots of homework that evening, so it’s looking at this with her once she gets into Year 11. Even 15 mins a day helps.
Revision ‘light’ that has worked for my ds has been watching Free Science Lessons/ My GCSE science/Physics Online videos. English Lit wise Stacey Reay and Mr Salles/ Mr Bruff for English Language. He likes History and Geography and watches things anyway on these by himself. RS it was textbook/CGP revision books.
I genuinely didn’t feel just watching things would work, but he refuses to do notes a lot of the time so at least it’s something. For Science he’s been getting 8-9 grades, so it must do something as those particular resources online are excellent . Maths I got a tutor to help him through the harder questions on past papers and this was really useful in him just not giving up when the question got tougher.
Making revision notes when they have end of unit tests is really key, especially in the content heavy subjects such as Literature and Science- there’s no time nearer the end of Year 11.
Just helping them find the way to revise that works for them as an individual .
I made him do condensed notes and computer mind maps initially ,which he didn’t like, but drawing topic notes onto a big A3 poster and flash cards work for him - which is the opposite of my dd.
The main thing is it’s a waste of energy (and argumentative) to enforce too much time- as they just won’t work (my dd used to hide her phone under a textbook!).
For A levels I’m planning to get him a new comfy chair and desk area to work- so maybe organising the area as she would like might be a motivator.
Making sure there’s a balance between what she wants to do (my ds would game all day and night)and what she needs to do.
I think it really helped me sitting down at the weekend and watching things with him and discussing them. I did most of his poetry notes as even though we watched things together he had no decent notes (he lost his Year 10 poetry notes and his school ones were not up to much). I felt just typing the summaries up then talking them through saved him from not doing it as English isn’t something he likes. I eventually made him character and theme summary cards on Romeo and Juliet and An Inspector Calls as I like reading and could bring together his notes and revision resources into a more useful summary, so it wasn’t so overwhelming in a subject he doesn’t like. I did not do any of this with my dd as there was no need.
If this seems a bit overkill I just think of it as me plugging the gaps and organising him. So giving him the resources.
Ultimately they have to want to do well themselves. There’s quite a high reward factor in education in doing well, but it’s hard to see that when you’re a teenager.
And ‘other parents’ always in your teen’s version let their kids stay up until midnight on their phone and are completely non pushy.
It really very much depends on the personality of your dd and what works for her though!
