A good while back I took a lesson with a teacher from the Cambridge Music Program (if that's what it's called?) And they basically spent the whol lesson evaluating my playing for a "grade". By the end, it was decided that I could play somewhere around grade six, though we apparently didn't have an "official" evaluation. So... is this good/bad? What kind of well-known pieces would someone at this grade play? They didn't tell much about it, so I'm really confused...
