Hmmm.. Pherhaps you should change your Beethoven Sonata. I agree with the others that the third mvt should not be left behind. Though, it's quite hard and demands alot of time and effort. I would pherhaps recommend Pathetique. There's also a mvt, the second, which makes women cry and grandmothers faint. And neither the 1st nor the third are so difficult that they should be looked on as a project each.
