I feel stupid asking this.. but...
I hear a lot of people mentioning grades?
Is this based on Certificate of Merit? Theory? what? O_o *confused*
I'm thinking of piano mostly , by the way

When people talk about grades on this forum they are usually rererring to the graded exams that this board has and the level you need for each exam. If you have a look at the 'exam' section of the site it may give you an idea as to what they are talking about.
