1 to 1 lessons, tutoring both GCSE and A Level further mathematics, already achieved 99 in maths and further maths, predicted A*A* in A levels. I have plenty of experience tutoring a multitude of students from failing grades to top students, and in all cases nobody has achieved less than 6 in GCSE and B in A level. Will happily provide support and examples, along with writing a specific programme for each student, to focus on the topics in which you struggle most with.
