Try to be on time or early for the class.
Wear your shoes between the changing room at the mat.
Bow before you step on the mat and before you step off. This is a sign of respect.
Try not to shout loudly while you are in the dojo. You should try to conduct yourself. Treat others how you would like to be treated.
Don’t talk while the instructor is demonstrating something.
Stay humble, don't brag about who you tapped out and how tough you are. Sometimes you're the hammer & sometime you're the nail.
Wash your gi after every session. Nobody likes the smelly dude.
Traditionally, the unspoken rule is that you do not ask a higher grade to spar. However, if you are polite and respectful, most senior students won’t mind if you do.
Try to view your sparring partners as people who are there to help you learn. If you go excessively hard with them, sooner or later they are going to go hard with you.
The more you relax and let go of the outcome, the faster you will learn. The harder you try to squeeze and muscle your way through every situation, the slower your progress will be.
Be CAREFUL when applying submissions. Many of the injuries that occur in BJJ are caused by students who lack self-control and apply moves with too much brute force.
Be aware of those sparring around you. If your area of the mat becomes crowded, move to another place. Lower grades always move out of the way of higher grades.
Don’t put your hands or feet on your opponent’s face.
When the instructor calls time, STOP. Do not carry on trying to achieve your position or finish your submission.
