Keep on training choonbee!! Your school sounds a little like mine in that we don't have yellow belts either. In our school you go from white to white w/green stripe to white w/2 green stripe to white with 3 green stripes then you test for green belt. Let me tell you all that time with a white belt kept me humble and was a big motivator to move on to my green belt.
I better close for now because it is time to go to class. Yeah.
