Online GCSE Maths Revision

[TheFabulist]

Hi everyone, my daughter is sort of averaging 80% in her Maths right now. She is in Year 9 and she would like to improve her Maths. Trouble is, I am rubbish at Maths (single parent currently as partner working overseas) and I cannot afford a tutor. Are there good online resources she can use every day for about 30 minutes to an hour, to gradually improve?
Thank you for any/all recommendations, and please tell me if they made a difference to your kids.

Mathletics?
My maths?

Teachers and people on here have strongly rated the videos and exercises on Corbett maths.
Also mentioned maths pad.
Good luck to her.

To answer the second part of your question - both my children used mathletics (log in was provided by the school). It was useful to practise what they had covered at school and could work on the topic at a higher level if they wanted to.

Thank you, both! Going to check out all these resources now. Very grateful
