Anna, don't know if you follow HOL on Facebook, Biz Pears left this message for you on our page I know a lovely, young maths whizz who has been tutoring Kumon maths for one-and-a-half years, for ages 3 to 16. She has an A* in GCSE maths, A in C2 and C1 maths. She's currently studying further maths at AS and A in maths A-Level, and expected to get As in both of those. She has tutored a few of my friends' younger brothers and sisters, and we'... See moreve had great feedback from them. She's someone who really plans engaging ways to make challenging topics easier to understand, and loves the subject, which is always a bonus. If she sounds like the kind of tutor you're looking for, reply on Facebook.
If you're not on Facebook, Biz Pears is this person and maybe you could leave a note on her page
