The beginners grade spans ungraded to orange.
Intermediate level is green - 
brown (part 2) - and there is a massive ability gap between those two levels.
Yet, it pales in comparison to the experienced, expert and advanced syllabus: 5 belts of hard material in which you are typically learning and applying a new form with every dan grade.

I recommend patience.
If Sifu thinks that you are ready for something, it will feature in your grade.
