You can chose whatever you want, except those two pieces. I was member of the jury in my old school, and whenever someone entered and said that they would play any of them, everyone stopped listening, because everyone knows they wont be played very well. Even if you play them well, it will give a bad impression to chose the two pieces that are that overy played. I guess your going to apply to a folkhögskola?Better to play the mozart sonata you're playing and a slow scarlatti sonata. The prelude wont show anything, neither will Moonlight 1st, unless you play the whole sonata. And never ever pick a piece because they are the easier part of something. It's as stupid as not playing something because it's easy.
