Secondary School - maths, chemistry and physics tutor

I have completed Advanced Higher studies in maths, physics and mechanics at George Heriot's school in Edinburgh and will be studying Mechanical Engineering at university from September. I obtained 5 As in my Highers last year which included maths, chemistry, physics, english and geography. I have a younger brother whom I have helped with revision for National 5 exams in maths, chemistry and physics in particular. My brother believes appreciated my support and said I was good at explaining concepts in a clear and calm manner.
