Year 8 preparation for Maths, History & Geography

[Canon]

DD is moving to year 8. Please kindly share and advise most friendly websites that come with practice papers & revision.

The subjects that we most need help & guidance with are: Maths (will be put in sets), History & Geography .

We are not looking for a tutor. Much prefer the DIY way to support her to explore weakness and build on exam techniques. Thank you.

I'm rather out of date and I'm sure others will be along with suggestions but have you tried BBC bitesize?
