Learning 10 pieces music in 20 hours

Tonight, in concert band we will sightreading 8 to 10 new pieces of music that arrived last night and this morning. I am following this protocol to be ready.  

1. I immediately printed the music. 
2. I created a new YouTube playlist of the pieces. 
3. I studied the scores while listening to the musical recordings. I made note of the tricky bits. I did not necessarily listen all the way through, just enough to get a sense of the part. 
4. I put aside all the music I can easily sightread. It will be read for the first time tonight.  
5. I have made note of the tricky bits in the three remaining pieces: one measure in one piece, one section in another, and then put the third on the music rack for immediate attention later this morning.   
6. I wrote in the stickings on the two easier pieces in the trickly passages. 
7. I am preparing to practice the one tricky piece with my pencil, eraser, recording, drumkit, music ready at hand.  

 I will let you know how it turns out tonight.
