No need to grade yourself. Add a few works you've already worked on — recent ones preferably, not necessarily the very last — and say whether they were too easy, suitable or too hard: What do we play next? infers a level on the same 0-100 scale as its whole repertoire, then suggests what to play next. The diagnosis covers piano, violin and cello: suggestions follow the instrument of the works you add.
1. Search above for the last 3 to 10 works you've actually worked on (piano, violin or cello).
2. For each, say how it felt: too easy, suitable, or too hard.
3. What do we play next? estimates your level and suggests works to consolidate, progress or take on a challenge — each suggestion is justified by its difficulty score.
