Regional differences in the proportion of top GCSE grades have become more prominent in England since Covid.
Just under a third of GCSE grades were 7/A and above in London, compared to just over a fifth in the North East and in Yorkshire and the Humber.
The gap between the regions with the highest and lowest proportions of top grades is 0.9 percentage points wider than it was in 2019.
Some Level 2 BTec pupils who were due to get results are facing delays.
Across England, Wales and Northern Ireland, students have been receiving results for GCSE, BTec and other vocational and technical awards.
