DS is entering his GCSE year. Not especially academic, has to work really hard to get results. Is predicted 4s & 5s. He has dyspraxia and has had a maths tutor since year6.
School don't seem to be teaching how to revise. Just advised to purchase the revision guides to each subject and then make mind maps and/or flash cards if they'll help.
We are building a revision timetable to give him some structure but it's no good just to add "science" but need to be more specific eg photosynthesis otherwise he'll go off on a tangent.
How does he learn which revision technique(s) actually suit him? Which are most effective? Any tips or advise is gratefully received.
