Whilst you'll be able to find less expensive tutors (and more expensive ones too), they may lack my direct teaching experience or a complete grasp of the whole course, for all exam boards, including international qualifications.  I have motivated hundreds of students through A level Physics exam courses (and many more through gcse courses), many of whom have attained A and A* grades.  I have a thorough knowledge of exam technique and preparation skills.  I have also been the exams officer at my school, so I have a great working knowledge of the procedure from that point of view as well. I can ensure that you have a clear view on what is required to gain full marks in each question and this means I can thoroughly support you with exam preparation to ensure that you reach the best grade possible.
