My Nidan test was a surprise. It was like regular class, only my sensei was working a lot with me that night. Not really correcting me, but nailing me with attacks, and throwing me very very hard.
Afterwards he bowed and said "Congratulations"
Were you awarded the Nidan from Southlake aikikai?
I can't see Dallas Aikikai granting any dan with only the dojo sensie approval because it is a federation dojo.
