Brazilian Jiu-Jitsu kata

I can't find any Brazilian Jiu-Jitsu kata, so I am going to make my own. I really think this is the best way to help me remember how to do the Brazilian jiu jitsu techniques.

Jaw Pain

For the last few days now, my jaw has been hurting. I went rolling yesterday and a guy was trying to pass my guard. He was trying to stand up, or something, anyhow I was at a 90 degree angle and I could feel my jaw, starting to hurt again. Does anyone know why this is? And if so how to stop it? I don't have a mouthpiece, could that be why? I have not been hit in my jaw or anything.

1st tap-out

I made my first two tap-outs, yesterday. Both were by kimura and both were on the same white belt, However he has been doing BJJ longer than me. Then I roll this the big ass blue belt, who with was very informative. He was a really good teacher, but now I have a lot of Bjj in my head and I think I am going to mist things up. Well, I know I am: I am getting all the escapes from side mount confused. But I was able to do it right one time on a blue belt. Also, I cannot seem to use the sit up sweep. People don’t sit up for me to do it.
