After i passed my level 4 exam for piano i decided to quit. i was about 14 i think. Now (19) i've decided to start again and see how it goes. The first piece i approached was Fur Elise and found it challenging but doable, and after a couple of weeks i can play it well. But now i really don't know what piece to study, mainly because i'm unsure of what level i am at. Being able to play Fur Elise, must mean i'm about 4/5? Are there any nice pieces you suggest at around this level?

Thanks a lot for reading.

P.S. I really like Bach's Sinfonia 2 in C minor, about what level you reckon that is?
