Hi all.   Each school or dojo have diferents rules for granding, special in black belts.   As I can read in the post some said 3 years others 8...   My question is:   how many days a week?   3 years (one day a week)? = 124 trainig days   1 year (6 days a week)?     =288 traing days.   Can you see the diference?   In my dojo to be a black belt you need 700 trainig days. +- 8 years.   Osu.
