Beginning to letter B needs to be VERY good. This means working on more than just notes/rhythms. Preferably learn up to letter C. Super-duper over-achievers can certainly tackle to the end of the piece.
Beginning up to measure 22 also needs to be VERY good. Same criteria as previous piece for what that means. Over-achievers may also work to the end on this piece.
PLEASE, PLEASE, PLEASE, be practicing! I will know if you aren't, and your grade will suffer for it.
