Your probably better off waiting for the next one now, as you'd only have a couple of months with the current syllabus.
Piece wise, I think alot of people did the following:
- Scarlatti
- Mozart
- Arensky
They seem to be the easiest for most people. There are a couple of really difficult ones in there two, which are great but significantly more challenging imo - Beethoven Op90 Mvt1, Schumann Intermezzo etc.
