Singlet is mandatory.
Advice: pick your opening attempts as something you could do for 3 EASY reps.
Save your third attempts for PR's, use fourth attempts to set new records.
This is your first EVENT, just get your feet wet.
Try and go 9/9 on attempts.
After your lAST attempt make sure you SHAKE THE HANDS of ALL THREE JUDGES and tell them THANK YOU, NO MATTER WHAT!
Above all else...have fun.
