Year 12 art a level advice? 'Predicted C'

I chose psychology, product design and Art as my A-level. Predicted A-B in PD and psychology. Today our art books our marked in 15 minutes and the teacher sat down and talked with us. I've done a lot of work over the months and have high quality work but she said my book was worth a C. I'm worrying because if that's the case I have 8 months left and I want to get into University.

Is there a particular university of course which you are targeting? Do you know the grade requirements? How do your predicted grades of ABC compare with those requirements?

Targeting Graphic Design in Loughborough or Falmouth mainly at the moment.
