What Don said.
Failing something isn't a catastrophy or even a problem. It's how we learn. YUP we fail our way to success. Only you know the truth about the test.If you do as Don suggests and look at the whys then you'll come up with a plan to do better
Many would quit after failing the test. you admiting it publically and asking for help sounds like a guy who won't take no for an answer. Those are the guys who succeed
Truth is we learn more from our failures than we do from success.
if you feel you simply choked the test....for some reason I get the feeling it was part stress and fatigue which is total conjecture on my part there are tools that will help
First you already know prety much what to expect so the fear of the unknown is eliminated
2nd Know the material. rehearse it like an actor rehearsing a play. Imagine the audience and opponent
practice the moment before and after the technique. Using the image of a WARRIOR and presenting that nomatter what happens good or bad will carry the event because preseption is reality.
remember to breath fully and explore the breath in the technique during rehearsal. How you practice is how you play
Have a FOCUS, of which the wARRIOR image is a part, but I would personally use "I move with a feeling of EASE" or a radiating image of fire(passion). rehearse using the feeling of Ease Focus because all great actors and athletes make it look easy. Use it as an affirmation. FOCUS on that and let everythibng else fall by the wayside. It takes the FOCUS off passing or failing a test, which is out of your control because your not the judge and puts it on whats important doing the work. If you work with the FOCUS and trust , it will carry you to amazing heights.
Some of this is high level actor craft which is my background but Olympic athletes use it as well.
hope it helps
