Math tutor teaches math from Primary to A Levels

Hi, I have a master degree in Chemical Engineering and Process management. I also volunteer at IChemE (Institute of Chemical Engineering).
I have studied a foundation degree for one year at London South Bank University On Campus to be able to start my university degree, the course was level 3 or A level equivalent and I had to study Pure Maths, further Maths, science, English and Chemistry. I had in total A* for this degree and feel really comfortable teaching them to someone as I used to my fellow colleagues and my friends and family.
I mainly teach primary students as I understand that the best students start learning from the base but nevertheless, never is too late to learn maths.
