Bad GCSE ART grade -AQA

Im just wondering if anyone elses AQA gcse art grade was not expected as i got a D in my art and design gcse but i was predided a B atleast. A girl in my class that was predided a A* only got a B. No one in are class got higher than a B. Now i dont no if it was are teacher putting are hopes up prediding to high or if something went wrong in the marking of AQA. And im not sure what to do because i wanted to do art in college and im not sure if i can anymore. Im thinking of getting my art remarked or to call AQA and see what they say because we were all undermarked.
