I'm so much the opposite. I'm just lucky - it's nothing I've developed, so I can claim no pride in it. For my BB self-defense test (the hardest single part of the testing, about an hour of responding to one attack after another), I did little prep. I figured I'd done all that in the years of getting to that point. I went to a regular class or two that day, I think, then did my test. I wasn't spectacular, but I passed easily. I think a lot of my test results are as much an indication of how relaxed I am at testing, as they are an indication of what they are meant to test. I wish I knew some way to lend that to others.
