First set of pieces to play

I figured it doesn't help if I randomly select music pieces to play, so as the first round, I picked 3. 

1.  Mozart K332 (https://www.youtube.com/watch?v=hn45vo56NcM)
What can I say about this one?  I like Mozart's composition in general.  I particularly picked this one because it's one of my Grade 8 exam piece.  For those who've prepared piano exam, you know how many times you had to practice before going into an exam.  But after all this, I still like this one.  

Where I'm at?  I think for all 3 movements, it's generally ok.  There are few places that I made mistakes easily continue to have this problem.  I played the 1st movement the most, so I guess it's better among the 3 movements.

2. Chopin Op. 18 Grande Valse Brillante (https://www.youtube.com/watch?v=LG-E4PVGQSI)

This one might be an easier start to get into the Chopin pieces.  It's pretty much the first Chopin waltz that I've played many many years ago. :)

3. Bach Prelude and Fugue XI (https://www.youtube.com/watch?v=L0X9KVlbMEc)

This one again is another exam pieces.  All I remember is page 90!!
