Last year we started implementing colored sashes, and it was fine. Lately though, a couple of students have in two months been promoted over students who have been attending regularly for nearly a year. A few of the other lower level students are becoming discouraged, and to be perfectly honest I am as well. They say they'll be testing to chum kiu in 3 months, but the fastest anyone else has gotten to that level was 2 years. What's more is that one of these people has developed an ego, and has been impatient and short with other students (although nobody ranking above him). I have never questioned my instructor, but I am starting to lose faith in the integrity of my school. And to be honest, I can't tell if I am just needlessly bitter. How do I address this? Any advice is greatly appreciated.
