Creative degrees in the UK require you to follow the system in order to get a good grade. It doesn't make a difference whether your final piece is the most stunning work you've ever produced if you don't do the legwork.
You get 25% of your marks for Research.
25% for Development.
25% for Showing an Understand of Technical Skills and Theory.
25% for your Final Piece.
The degree show is the only exception to this rule. This is me just having fun and designing whatever I wanted for once.
