Mostly, just an oral exam...
Sensei: "Nick, you were a brown belt in tae kwon do at one point weren't you?"
Nick: "Yeah"
Sensei: "Do you still have it?"
Nick: "Somewhere, probably...."
Sensei: "Why don't you just start wearing that instead."
Nick: "How about black belt instead?"
Sensei: "KIYAAAAAAAAAA!!!!!!!!!"
Nick: "AHHHHHHHHHHHHHHHH...................ugh...." (rolling on the ground, moaning and crying sounds)
--------------------
Everything except the last three are true....or are they?
No they're not
So my advice for those that become very nervous for rank tests, just wear the same rank for two years until your instructor gets sick of seeing it around your waist.
