Students in England, Wales and Northern Ireland will be receiving their GCSE results on Thursday morning.
Results for vocational and technical awards will also be released - though some BTec pupils could face delays.
This is the first year group to have taken GCSE exams since 2019, after two years of cancellations due to Covid.
Overall grades for GCSEs are expected to be lower than 2020 and 2021, when grades based on teachers' assessments led to a rise in top marks.
But they are projected to be higher than they were in 2019.
