Lessons aimed at GCSE and A level students

First class mathematics graduate from Durham University, 7 years of tutoring experience, A* in A level maths, A* in A level further maths, 9 in GCSE maths. I like to teach by first providing a diagnostics test students to see where they stand with certain topics; then we can begin tackling what they struggle with the most. I believe in understanding and confidence over memorising formulations.
