Yay, I just got 2nd Kyu Aikido!
I know I made a number of mistakes (like not avoiding and getting a tanto in the stomach :-/) but I obviously did well enough.
Recently I've been practicing randori-no-kata, shichi-hon-no-kuzushi, randori-no-kata-no-ura-waza and koryu-dai-san; all a long way from perfect, of course. And what did they ask me to do .... left-handed Randori-no-kata, tanto hikitategeiko and some free play. Oh well, it's all good stuff.
The general comments about the grading, and I know some apply to me, was that it needed to be more flowing with more movement and "life".
Comments on my personal performance was that I was getting a reasonable amount of movement in the tanto hikitategeiko, and that my kata was quite good. They obviously weren't watching the whole time ;-).
