My daughter (10yr) did exam for her taekwondo black belt. There were 8 kids testing for black and one for red and a stripe. The whole group did very well. The gentleman in the suit is Grand Master Choi. He had asked Master Julio "how come this group does so well?" At a second thought Master Julio had his doubts - does this mean that other groups are bad?!
Anyway, I made a little YouTube video of Yelena practicing and later breaking her boards: https://www.youtube.com/watch?v=VfMAbJ2OBzo
