I started piano at 7 but stopped ard 3 months later(When learning to read notes). I got back to piano at 9, got up to some grade( i forgot) and stopped at 11. Now i am 16, trying to learn piano from a teacher again. So, how do i know which grade should i learn? Funny thing is , in my first lesson with that teacher , he started by teaching me Fantaisie impromptu =.=
