My DC have begun studying for their GCSEs at GS. They are both struggling with essay writing. It's most obvious in English, but is being carried through into other areas (history, geography etc) where discursive essays are required. I'm an older mum and it's been a very long time since I've had to do any of this

. Can anyone point me towards some useful 'how-to' books/ revision guides, so that I can see the required structure for these kinds of assignments/ exams? Thank you

Hello
I hesitate to ask, but has the school given no guidance on the required structure for the work that is being set? Your DC's first port of call should be their subject teachers if there is anything regarding the syllabus that they do not understand.
The school should have told you (or at least your DC) which exam boards it is using for each subject. All exam boards have the specification, teaching materials / marking schemes and sample assessment materials on their websites (some items may be 'teacher access only', but a lot is accessible). In our experience, schools have also offered study guides to purchase at reduced cost - ask if yours is intending to do this, before you rush out and buy anything.
If you indicate which school, someone whose DC have already gone through GCSE there may be able to indicate what your DC can expect.
