Understanding marks & grades
The Uniform Mark Scale (UMS) explained
When you get your results slip, you may find that your ‘final mark’ is different
from the score on your exam paper – the so-called ‘raw mark’. This is because
the majority of results are published in UMS marks.
The UMS is a way of turning the raw marks achieved in a unit in a particular
sitting into a mark that can be used to compare with those achieved in other
The UMS balances out differences between exams and is a way of making sure
people get the correct grade, no matter when they took a particular unit. UMS
marks from all the units are then added together to give you an overall mark for

Pearson (Edexcel) has developed a mark converter to help you calculate your
raw mark from the UMS mark published on your results slip. This will help you

AQA mark converter
AQA also has a tool on their website to convert your raw marks (the marks on
your exam paper) to UMS marks. The marks on your results slip are already UMS
marks. Your teacher will be able to give you your raw marks.

IT IS IMPERATIVE THAT YOU SPEAK WITH YOUR SUBJECT TEACHER BEFORE MAKING ANY DECISIONS ABOUT RECEIVING A RE-COUNT OR RE-MARK.
