I am playing this for my AS recital on 26th April, and I just can't seem to get the runs, especially the last page, and the scalic run F, G, A, Bb, C, D, Eb, F. I have been trying a lot of things, including scales in the 3rd octave (my fingers panic in the 3rd octave), and changing the rhythms and things...but no success

Any tips?
