Yeah, i should have thought about that.... well... i dont do exams or that kinda thing, so i dont really know a level as such...
To give an idea, the most recent works i can play confidently are:
Debussy- Preludes and Estampes (complete)
Ravel- Gaspard de la Nuit (complete)
Liszt- Transcendental Etudes No 3,4,5,6,11,12.
Don't really know their standard though, apart from the 5th transcendental etude, which ive heard a lot about on this site.
