Mokwepa, the standards vary enormously from country to country, as they do from region to region. One mans intermdiate is another mans expert. I've ridden in SA, NZ and Aus and it's huge. Also don't forget that the riding terrain dictates the sections. What might be considered a clubmans section in one place might be an experts section where there is little traction. Gauteng, having lived there myself, does not suffer from this problem!
Have a look on Facebook for the NRTC page. The guys there will be in a much better position to assist.
