It's about as difficult a piece as there is.
When I first came to this site, I noticed that this piece was one of the least-discussed major pieces of Chopin. Since it's one of my long-time favorites, I started a thread on it, and was shocked to find that one of the main views expressed was that it was one of the less-difficult major Chopin pieces -- like, that it was a piece that intermediate players could try if they didn't feel up to the Ballades or Scherzi. I know that such things are subjective, but.....not always. With all due respect to the other side.....OK, with at least a tiny amount of respect
....that's total baloney. I can sort of
understand the view, if what they're thinking of is (as is sometimes the case) "except for the hard parts."
Or if they're not talking about aiming for anything beyond a cautious and timid performance.
You don't have to worry that the people doing the selection at the college will have that view. They'll regard the piece as it really is.
