I have been playing the piano for 2 and a half years, and just finished my grade 6 (distinction).
My current practice time is 1 and a half hours, and I divide it as shown (with my current pieces i'm working on):
10 minutes: Hanon warmup and scales
20 minutes: Czerny exercises
20 minutes: Bach Partita 5 Praeambulum
20 minutes: Kuhlau sonatina
20 minutes: Chopin waltz
How does this practice schedule sound? Do you think I should only work on 2 pieces a day or even 1 for a longer period? Would you spend longer/shorter on say scales/hanon or czerny? Or maybe increase or reduce the day's practice time?
