Distance learning recommendation

[DavyJones119]

We are home educating our children. I was able to teach my oldest IGCSE maths myself, but it's not working for our second daughter. I'm looking for recommendations for a distance learning provider. It would have to be Edexcel because the only exam centres anywhere near us only do Edexcel.
She also fancies Psychology, which I know is GCSE but still seems to be accessible to home educators. Any recommendations for that too would be much appreciated.
Thanks in advance

Check with someone more knowledgeable, but I have heard that unlike other subjects, in maths the various (I)GCSE specs are very similar, so you might not need Edexcel specifically. But maybe you already know more about that than I do, since you helped your eldest child with it.
