Yu-Jin had a taekwondo grading on Saturday. It came as a bit of a surprise as he had been struggling with his taeguk five pattern before we left on holiday and then he didn't do taekwondo for three weeks. Lo and behold we return and he's finally worked it out. His performance wasn't as good as it could have been, which would have a lot to do with the pressure, but this is the way to make you feel responsible for your own actions. Nobody else would be responsible if you fail. Well done my boy for achieving your fourth gup.
Congratulations on becoming a 4th Gup.
It appears that tae kwon do associations around the world have different levels of skills required for each test and colour of belt associated with it. Here's a video of tae guk o jang (tae guk five poomsae pattern) that is the highest level pattern for a prospective fourth gup to achieve.
