What is 'raw mark'? Watch
A raw mark of 26 falls within the C range. Surely this cant be what I'm thinking it is.
ie, the paper was out of 40 and you got 26. That it a raw mark.
If they decided to make 24 the boundary for an C, then 26 might get you a scaled mark of, say, 64 out of 100.
They turn raw marks into scaled marks to make papers equal.
edit: as above, a UMS mark is a scaled mark.
