Hello piano street as you can see this is my first post and it's another good 'ol boring Atcl help

Well this year I just scraped through grade 8 and next year i'm doing an Atcl (I want to at least get an Atcl before I finish high school). My teacher and I have agreed on this:
Bach - prelude and gigue from Partita no.1 in Bflat maj
Chopin - Ballade no. 3 in Aflat maj
And possibly Debussy - la plus que lente
Now for the big sonata piece, my teacher told me it should be a classical piece for the obvious period reason

. Now I love most types of music from early baroque right through to techno/hip hop but stopping at 2010 music onwards of course (jb, lady gaga ughhh), but somehow, I don't know why I just can't enjoy playing a classical piece, especially Mozart...

(sorry...). My teacher tried to get me to do a Haydn piece he loved and I sympathized with him but I just can't see myself practicing them really...
So what do you think I should do for my big piece? Which classical piece do you think can convert me to a classical believer? I have played the whole Beethoven pathetique sonata and I played a bit of the Schubert in A minor D.845 and loved it but with Chopin already being romantic I'm not so sure... So anyways if someone could help me would be great thanks
