Tips for mello audition for SCV?

Hello! I’m planning to really LOCK IN through out the next year on marching and mellophone, I’ve been super into drum corp since 2023, I legit don’t listen to any other music lol. But I plan to audition for SCV next season, there brass is so incredibly loud and there Mellos blow me away every year. Are there any good drum corp specific practice plans and tips so I can prepare for the audition?
