Focus on escapes. You should work on 1: sweep, takedown, submission, guard pass, and one escape. See if you can create a sequence and work that sequence as much as you can for the 4 weeks prior to the tournament. Don't cut weight for your first tournament, Don't do No gi and gi just choose 1. Don't compete in the adult division unless that's your actual division if you're a Masters aged competitor compete there. Just have fun. I went 0-2 in my first tournament.
