Maths teacher who focuses on GCSE

I am a dedicated, hardworking, very supportive teacher. Maths is my subject because I really enjoy seeing the thinking skills develop as I work with a student.
I have spent 25 plus years working with people who are aiming to achieve their grade 4 or above at GCSE.
My on-line lessons will cover basic number work practice without a calculator, followed by retrieval practice of a previous topic, and then new material. New material will come from gaps in student knowledge, or requests to revisit or go over a specific topic.
I have several years experience of working on-line as a maths tutor.
