Cheerleading

I'M TRYING OUT FOR CHEER!!

Honestly, I am kind of nervous since I tried out before when I was in 8th grade, but I didn't know what I was doing and was just unprepared. Now that I am a sophomore, I am trying to be more prepared and try to start working out and practicing some cheerleading moves. Please give me some tips to help me out since tryouts start May 12th.
