According to who? There was I thinking that it is the most difficult of the five!. The second movement is quite easy, the outer movements are anything but.
I've seen it written a couple of times in books that I have here. As soon as I find them, I'll quote them. It's not my opinion. I agree that the 1st and 3rd movements are probably the hardest of the five, but as the OP says it's for a player of grade 8 standard, s/he may/may not find No 5 easy.
But then Fsharpminor says none of them are particularly difficult..I guess it's down to personal opinion as always. But I bow to greater wisdom.
I'm more likely to tackle the opening movement to No 4 before I even consider No 5.
