If you would like- I could be.

I've taught maths in English secondary schools and I've also taught it to children on this site before. If you could tell me his age and the kind of things he's studying, it would be really useful. Particularly if you can send me a link to his school syllabus. Please message me if you'd like to ask more questions or feel free to book a trial session if you'd like to discuss it further.
