1)It took me 2 years of piano, then a further year of self teaching before i started on the etudes, they are not difficult, they just require a huge amount of skill2)You can't play an etude perfectly, nor can you learn a whole etude and master it, they are for practicing your fingers, not for other purposes, a practise piece3)They are and they are not, they are difficult technically, but not musically, if you want difficultly from chopin, check out his Ballades and his Scherzos

after a good warmup (with a real piano)self can play it at that speed (trying it cold can be acheful)whether the piece is still recognisable is questionable though
