Help with piano, theory or composing for exams

I am a graduate in piano and composition from the Royal Academy of Music, and hold an M.A in Music Performance Studies from City, London University. I have over thirty years' experience as a teacher of pupils aged 6 - 75 in range of musical subjects, principally piano but also in particular, music theory, and regard myself as a specialist in helping pupils achieve Grade 5 theory. Additionally, I have long experience of helping pupils with elements of GCSE music, particularly composition, and to a lesser extent, 'A' level music.
