The most important thing necessary to achieving high grades is understanding the content. No matter how difficult you find it I will ensure I explain it in a way you understand. Questions are the best way to learn, so no question is a silly question! After learning the content I will make sure you apply it, by completing practice questions and reviewing any mistakes made along the way. This will ensure you are prepared for the exams, and know what style of questions to expect. Maths will finally seem understandable and no longer your hardest subject.
