I have to agree with Mr. Smith. I train all my students to start training for their test, the night after they took the last one. If you train hard, your test should be just another night on the mat. My only other advise is not dwell on the techniques, but everyhting else. Look at your distancing, your timing, your body posture, and how you leave your attacker when your done. In my art, we leave everyone on the ground, your technique is not complete until they are down, and then how you move away from them when your done. If you leave someone standing, look how you leave them, where you position your body in relation to theirs. Check things like posture, focus, and try to respond to what the attaker does instead of just doing technique. Its all these things that will get you to another level instead of just concentrating on technique.
