Feel free to post your testing requirements up - it would be cool to find another schedule which is similar. [I assume by 1st Dan it all adds up to about the same thing, as everyone gets their ranks through Hombu and/or through a 'super Shihan' like Tamura Sensei, etc.]
Lots of folks get ranks not through Hombu or a super Shihan. I think its more a case of knowing how to play the scales in any key. Then you are ready to start learning to play music.
That's a long test list. Looks like fun. How many uke will you use during a test?
