Linear and unitised qualification grades are calculated in different ways. We've provided some more information below:

If you have any queries, please speak to your exams officer. In particular, if:

• You have trouble understanding how your grade has been calculated. If necessary, your exams officer will be able to submit an enquiry via the appropriate route.
• You need to find out if special consideration was taken into account in calculating your grade and how it was applied.

You may also find our factsheets on examining explained useful.

Linear qualifications are designed to be taught continuously over the length of the course (typically two years for GCSE or A Level), and all the assessment takes place at the end of the course. As they are not broken down into chunks, linear courses give more scope for teaching and assessing across topics, and drawing topics and ideas together.

Since candidates take all the assessed components of a linear qualification at the end of the course, there’s no need to combine marks from assessments on different occasions so there’s also no need for UMS marks to be used. Marks for all the components taken by the candidates are just added together (allowing in some cases for weighting of certain components) in order to get the candidate’s total mark. And it is this total mark that will determine the candidate’s grade – the candidate will not receive UMS marks, because in linear qualifications they don’t exist.

Take a look at our handy info sheets:

Unitised qualifications are designed to be taken in chunks, or units, throughout the course. Marks (and unit grades) are accumulated along the way, and when all the required units have been taken, an overall grade is issued. Since exam papers can vary in difficulty from one series to the next, a common scale is used (called the uniform mark scale or UMS) to ensure marks gained on an easier paper do not advantage candidates compared with those who gain marks on a harder paper.

How is the UMS calculated?

1. Students sit the exam and the script is marked by an examiner according to a set of strict criteria. The examiner then calculates the raw mark.
2. An awarding meeting takes place, with a group of experienced senior examiners comparing papers from that year with previous papers and statistics. Using their professional judgement they decide what the grade thresholds should be.
3. The raw marks for the unit are converted to a UMS.
4. Grades are awarded.

The grade of the overall qualification is calculated by adding together the uniform marks achieved in the individual units. This gives candidates a final uniform mark which is compared against the overall UMS grade boundaries.

For unitised qualifications, both the unit uniform marks and grades, and the final uniform mark and grade are given on the results slip.
