So I’ve just received the detailed feedback on my dissertation. My overall mark for the module is D1, so I think my overall marks look like this.

Assuming these grade-bands were used throughout the marking, and that my marks were in the exact centres of my bands, my average mark works out as 83% and hence my average grade would be D2.

However, the mark that counts is the dissertation mark – this shows that I can do research in my chosen field. I knew this, but now I have comments by research professionals to prove it. So roll on graduation!
