Help with all district audition tomorrow

I play trumpet, and im doing an all district audition tomorrow. it’s late at night, and i haven’t had time to practice at all the past week.

How do i go about this? Tell them i don’t know the two octave concert A major scale? Or do i just try and fail miserably?

I think i got sight reading down, and i only know 2/3 of the solo cause i found out two weeks ago. I know im not making it but i don’t wanna embarrass myself.
