Debussy – Images Book 1: Hommage à Rameau
Mozart – Rondo in A minor, K511
Liszt – ‘Sonetto 104 del Petrarca’ from Années de pèlerinage, 2eme année: Italie

Thanks for sharing your programme; I look forward to hearing it on Spotify and reading up on your progress through the blog.
I have begun studying for my LTCL too and was considering preparing pieces that are present on other exam boards’ diploma repertoire lists with the intention of picking up multiple diplomas within a short space of time.
