Online Maths Tutor for 10+ and 11+ maths examinations

Currently studying at Trinity School Croydon on an Academic Scholarship, I do Maths, Further Maths, Economics and Psychology at A-Level. GCSE grades were 10 A Star equivalents ( including maths and further maths along with the core subjects) and 1 A equivalent. I've tutored in the past however I'm moving to online tutoring, can help teach maths to a 11+ standard and potentially help with some GCSE material. In terms of lessons I'd see what the student's syllabus is like and try identify and fix any weak points within it as well as helping with correct exam technique.
