How do grades at dissertation compare to overall classification?
Do students tend to better, on average, because they picked a subject that is close to their heart and interests them. Or do they do worse because they don't plan the time properly and get overwhelmed. Or are dissertation grades about the same as general overall grades. Or all of the above i.e.there is no general pattern. Oh, and I suppose there could be different patterns across different subjects, too.
Just idle curiosity.
