Focus on developing speed and clarity in rapid scalar and arpeggiated passages.

You should be comfortable at Henle level 4 — meaning you can already play level 3–4 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
