Alexander Scriabin's 'Allegro Appassionato' is a virtuosic and tempestuous piece that embodies the passionate intensity of his early Romantic style. It is characterized by its dramatic flair and demanding technical passages.
This piece demands significant finger strength, speed, and the ability to execute rapid octave passages with power and clarity.

You should be comfortable at Henle level 6 — meaning you can already play level 5–6 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
