I just checked your dojo website, you are affiliated to the Federacion Latinoamericana de Aikido, si you have ties to Yamada sensei. Since Yamada presided over my shodan test you may find it interesting to check it out. I started a thread a while back with links to my test on YouTube here:
I have to echo Rolf's comments, it's the years of training to get to the test that count. If your curious about the tests in you own group, ask your sensei or better yet make sure you are there the next time someone you know is testing. Overall, I wouldn't worry too much about the black belt, certainly not until sometime after you have achieved first kyu.
