Why didn't you bring it up yesterday in the dojo ? I think I could have helped you a little - at least with the 'yokomenuchi - yonkyo'. I've been pondering that one too, since I might go for the 2. kyu same day.
With regards to the choking technique and the roukkyu they are in my opinion both outside the curriculum for this grading.
Have you found an uke yet ?
Peter and Trine are going for 2. kyu as well, so I guess I might as well try to tag along, though I have been concidering skipping the test this time
