I'm planning on applying for a foundation in music course(contemporary) in a uni here, and I'm wondering what sort of pieces should I prepare.

The site says that I need to prepare three pieces in contrasting styles, with one of them being a contemporary piece.

The benchmark entry for the course is a ABRSM grade 3 in both practical and theory so I don't think they expect a very high level of proficiency. I have a grade 8 in practical and grade 5 for theory from ABRSM, though I am extremely limited in my contemporary skills.
