What techs are they going to be examining you on? Are there hand techs (wrist releases, that sort of thing) that you need to cover and can focus on while you're awaiting word on your ankle?
We don't do wrist release sorts of thing until much higher up, we learn it, but it's not graded on until you are actually teaching it someone else. (In our school the higher grades teach the lower grades self defence), I know that sounds odd but the exams are long enough as it is.
It's probably easier to describe our exam process which I think may be a bit different from yours.
Well the process goes something like this:
Arrive and line up, Examiner arrives and we go through a light on the spot warm up with the senior instructor of our school. We do the two patterns of the lowest rank, then their techniques, the lowest ranks get asked their Korean terminology questions and the questions relating to thier patterns and ranks (belt colours etc), then they go sit down. We then do the patterns and techniques of the next ranks.... then their questions then it's us.
The next phase, starts with us 8th kups and belows getting up back into line, pairing up with the person next to us and doing "set sparring". Then after we've all been watched for what seems an eternity, we sit down and the 7th kups and above do thiers.
The techniques we do are blocking and kicking, we do it on our own though and no pads, just solo drills. My techniques for my grade are
-> Middle knife hand guarding block (part of pattern)
-> Lower outer forearm block (part of pattern)
-> Twin forearm block (the one that blocks the head) (part of pattern and seperate)
-> Outer forearm rising block (part of pattern)
-> Middle knife hand strike (part of pattern)
-> High forefist punch (part of pattern)
-> Middle Outer forearm inward block, followed by a middle backfist strike (seperate to pattern)
-> Wedging Block (seperate to pattern)
So for an 8th kup the techniques are really all upper body ones, but I do have to do 10th and 9th kups as well which are Front snap kick and side kick.
The final phase is sparring, 8th kup and below do no contact or light contact sparring (if both have sparring equipment) for three rounds picking a different partner for each round, after that the 7th kups and above do light contact sparring (they must have sparring equipment).
I'd be interested in what format your colour belt grading takes... I'll open another thread.
