"New GCSE grading system
It is higher than the legacy A* grade, and is only awarded to the top 20 per cent of those achieving grade 7/A and above.
According to figures released today, of the 837 students who achieved straight grade 9s this year, 556 – 66.4 per cent – were girls, and 281 – 33.6 per cent – were boys.
That means a higher proportion of clean sweep successes were girls this year – in 2018, the figure was 62 per cent.
The number of students with straight 9s in 12 subjects has doubled this year to 10."
