I have taught A-Maths for more than 10 years and I have students who initially failed in their school exams but went on to get B4 and above grades after my tuition!
My approach has worked with previous students and improved their results tremendously. I am a patient and responsible tutor. My approach is always start with a question and see the ability of the student to apply concepts relating to that chapter in the syllabus. Following that, I will select questions to be assigned to the student for discussion.
This method and my experience and personality have worked effectively for me and students generally find my approach easier to remember key concepts.
