receiving a "U" for an A-level paper

Hi everyone,
I am currently having my A-level finals in Biology (Pearson Edexcel). I already have enough UMS marks for the grade that I wanted (360 for a C). My question is: what happens if I receive a "u" for my final paper? Do I still get the A level? Or will it not be granted because one paper is "unmarked"?

Many thanks and best wishes!

You still get the A level.
