test length

[Kuma]

our kyu testings only last as long as a class(1-1.5hours), but black belt testing is an all day affair, is this average, how does this compare to your testings?

Like mostly everyone else's, it depends on what rank you're going for. My most "recent" (since I rarely get to do any kind of testing since they only do it 2-3x a year and out of state) promotion lasted a bit over 2 hours: kihon, kata, self-defense drills, tameshiwara, and 20 minutes of jissen kumite against 10 different opponents (1 every 2 min essentially, so you're constantly fighting a fresh opponent while you just get more and more tired). My sensei's was much much longer when he got his newest dan, as his kumite alone was 60 minutes. I had other things to worry about that day, I didn't pay too much attention to what he was doing

The higher the rank the longer the testing within my style. My Hachidan test took me a week due to the amount of the material per the grading syllabus.
