Can i get a C grade in dance gcse?

Ok, soo i did my dance gcse and i did my performance peice, choreography and set study. We send the videos of to the moderator. The moderator has wrote back to my teach saying that she only wants to see my set study? will this mean i will get a rubbish grade? because my grade is only coming from this piece? Everyone else is normal, but im the only one where she doesnt want to see my other pieces ... Does anyone have any advice for me?
