We don't have that rank in BJJ or Judo but by the time someone's earned their first rank in Judo (six months to a year and a half) or BJJ (a year to three) they've internalized the lesson that cavemanning your way through things is a bad idea and have begun to learn the basic vocabulary of responsibly dismantling a human body. They know how much they don't know, so to speak.
