I want to offer lessons to kids in years 7-9 to aid them with homework and understanding in school based on what they want to cove

Maths has always been one of my favourite subjects at school, I have loved it but have also found certain areas challenging. I want to help other students close to my age that I can relate to and genuinely help as I have been through the curriculum and tricky areas in maths not too long ago. I have just finished year 11 and have been predicted a grade 8/9 and hope to continue taking maths at A level.
