It will be GCSE results day on Thursday, and this year pupils in England will see more of their qualifications awarded under the government's new 9-1 grading system.
GCSE grade changes
The grading system offers greater stretch for candidates at the top end, with a 9 higher than the old A*.
It is not easy to make direct comparisons between the numerical grades and the old alphabetical system, except at three points.
Grade 1 has been tied to the old grade G, grade 4 has been tied to the bottom end of the old grade C and grade 7 to the bottom of the old A.
Under Ofqual's comparable outcomes system, a broadly similar profile of grades will be awarded as in previous years, assuming the cohort has similar prior attainment.
