Depending on how far along you are, that might not even be an option. If can you mention some of the pieces you've played, and maybe post some recordings of them in the audition room, it would give us a much better idea of what would be reasonable to recommend.For example, the best piece for developing the fourth/fifth fingers in the right hand is (to my knowledge) probably Chopin's op. 10 no. 2, which might not be an option if you aren't able to play most of the Chopin Etudes. Another example is 10/4 for hand independence, but that might be a bad fit for your current skills. Based on your statements, I'd guess these would be too difficult for you. However, I don't know what you're capable of, so I can't make good recommendations.Once you've had some pieces recommended, you should ask your teacher about them. It's very likely she knows more about what you're capable of and what your limits are than any of us.
