Confident or Nervous

I will be going for an audition as you guys know on the 16th october ,
and Man i am so not ready ( i think)
Me , My bro , Ben , and Evan are playing EnterSandman- Metalica
Me on the drums
My Bro on the guitar ( melody )
Ben on the guitar ( solos )
Evan on the Base .

Right now a day before the audition ,
I am wondering if i am ready or not .
The Drumming for it is easy , but i am scared i will make a mistake .
Omgosh SO MUCH PRESSURE !!!

How do you Handle It !!!

Well , wish me and my band good luck !!! :)
