Hey guys, i've got a school concert tonight and i play snare drum. The concerts in an hour and a half but im really not sure if i should go. Ya see, i dont really know the 10 pieces that were going to play because i have no music to practice, so i figure if i go then i'd just make the band look bad because this is a very serious concert that we're doing. But then if i dont go i dont get the 50 points for band class. so its kinda like A)go, "freestyle"- goof up the band or make us look bad...or B)dont get the grade.

what should i do?!
