Confused about revision books

[Slitherout]

DD is in Y10 and I'd like to get her revision books for each subject but confused about which ones would be best. We're in Wales so under WJEC board for most/all subjects and still under A-G grades rather than 9-1 whereas obviously new revision books are all advertised as for 9-1 GCSE's. Does this matter? Which revision guides would be best?

I'd be mainly looking for guides for Maths, English, the triple sciences, computing and RE if it helps. TIA!

I would ask the school what books they recommend.
You don't want to get books that don't contain the right stuff.
The school may sell them as they can buy in bulk.
With WJEC being a less widely used board there is probably less choice.

Has the WJEC syllabus in Wales changed at all OP or is it the same one that students took in 2016?
The reason I am asking is that my dd took WJEC English in 2016 (although we live in England) and I did buy some revision guides but have assumed that as they cover the "old" syllabus I wouldn't be able to pass them onto anyone.
