Sixty-one per cent were awarded level 9 and 95 per cent received grades 7 to 9.
The 192-strong year group performed exceptionally well in maths and sciences, with the top national scorer in GCSE English language.
Headmaster Neil Enright said: “This is a very good set of outcomes indeed, reflecting the talent and hard work of our pupils, the expertise and commitment of QE staff, and the support of their families.

“My sincere congratulations go to Year 11, and we look forward to the boys beginning their A-levels in September, joining our largest-ever sixth form.”
The results showed 85 per cent of exams were awarded grades 9 to 8.
All 171 boys taking GCSE chemistry achieved either a 9 or 8 grade.
Fifty boys sat Latin GCSE this year, more than twice as many as in 2024; 33 of them achieved grade 9.
Mr Enright added: “What is truly remarkable about these results is that they were achieved by boys who make time alongside their academic studies to take part in a huge range of co-curricular activities through our QE Flourish programme.
“It is the breadth of the whole QE experience which enables us to fulfil our mission ‘to produce young men who are confident, able and responsible’.”
