I don't think they really earned those grades. Not after two lessons! Do they really think they earned the rank? Our instructor say's he'll get us a black belt for five bucks in three days if we want. But does that make us a black belt. No!!! I worked for six years for my belt and truly feel like I have earned it. And continue to learn something new in ever class I go to. The belt you wear has nothing to do with you being a Martial Artist, the knowledge you acquire during your journey has everything to do with it. And I'm not only referring to the fighting skills obtained. The life skills are much more important to me.
