Convert raw marks to UMS

Some qualifications, such as new GCSE, AS and A Levels, are linear. Linear qualifications do not use UMS and therefore are not included in this converter.

For an explanation of how the new linear qualifications work check out our blog on how linear qualifications and grade boundaries work.

Use our raw mark to UMS converter to convert raw marks to UMS marks for any unit from the available series. You can:

Input one or more scores directly
See a table of UMS for all possible raw marks together with accompanying grades
Import a CSV containing raw marks for conversion and export a CSV containing the results.

For more information about raw marks, UMS and how grades are calculated, please see our guide to calculating your grade.

Converting UMS marks to raw marks

NB it is not possible to directly convert a UMS mark back to a raw mark as sometimes there are multiple raw marks for each UMS mark. You can, however, use the 'Show all scores' tab, to see what raw marks correspond to a UMS mark.

Choose a CSV file to upload and convert. You will be able to download the results.

Formatting instructions

The CSV file should consist of two columns: 'Candidate' and 'Raw score'. The 'Candidate' column should include a candidate identifier such as a name or student id, and the 'Raw score' column should contain the candidate's raw score for this unit. See this sample file for an example.

NB: If you upload a CSV file, please note you are not uploading data to OCR's servers or transferring any data across the internet. All processing of the CSV file is carried out in your browser.
