So that's a low-middle rank then, yes?
Not really, as the 1st dan is considered "beginner". So 3rd Kyu is middle "pre beginner"
It's a bit different in France. You start 6th Kyu, and go up to 1st Kyu, where you are graded by your own teacher.
You need to perform the techniques he announced. To give you an idea, I recently printed a book with all the techniques you need to know for these tests, there are 361 pages, so that's roughly 160 techniques.
I started again in October 2007, after almost 10 years of interruption, then passed the 5th Kyu in January 2008, the 4th in June 2008, and now will pass the 3rd in June 2009.
Logically, I should pass the 2nd next year, and the 1st the year after. And last, prepare the 1st dan... But I think I still need a LOT of work.
The Kyu rating are not very important as we don't have competition, it's more a way for you to evaluate your own level.
We also use it to know who is the more advance, and he "starts first". I mean, if when going to the training the teacher is not there (let say he is sick), then the guy or girl with the highest rank would default to lead the training.
And when we practice, the teacher shows a technique, explain it, and then we practice it.
We usually do series of 4. The attacker (uke) tries to grab or punch the defender (tori), then tori does the technique, and make uke fall or control him with a lock. And then we repeat it 4 times : 2 times on the left, 2 times on the left, 2 times ura, 2 times omote (omote/ura are not easy to translate, to simplify omote is entering into the attack, ura is slidding outside or it). And when we change role.
Usually, the most experience one (ie lowest kyu) start first, as he is supposed to show the technique to the other one.
And usually, at the end of the training, we do some "ju waza", free technique: tori can do whatever he feels like doing instead of repeating an imposed technique.
Or we do some randori: alone against several opponents.
