I will be trying out for my new school's freshman cheer team. Does anyone have any pointers so that I can make the team?

Edit: Just so y’all know, I know the basic things like smiling, being loud, and being sharp. I was on my middle school cheer team, but I dont know what will be different about high school cheer.

Update: Tryouts are tomorrow, and I am super confident in all of the parts of the tryout! Thank yall so much for all of the tips. I will update again tomorrow for the results!

Update: I MADE IT!! I'm so excited. Thank y'all for all of the help!
