I`m a high school freshman who took four years of piano lessons earlier, but haven`t had the time to take them in a while, although I still practice.

My Repertoire includes Johannes Brahms` Rhapsody in G Minor Op.79 No.2 and Chopin`s Waltz in E-Flat Op.18

Are Chopin`s Nocturnes (particularly opus nine`s and fifteen`s) and etudes (particularly opus 10 number 3,5,12 and opus 25 number 12) a bit too big of a step at this point for me? If not, what advice do you have. If yes, what are some good step up pieces? I was thinking maybe some Debussy and Beethoven are some good step ups.

well i really don`t know what would be good for you but i can tell you that i play mozart and beethoven and i didn`t even have piano lesson for 2 months but i had been playing a while without them. its about practice.
