Staff and pupils are celebrating after securing top marks in their A-levels at Wellingborough School.
A spokesman for the school said: “We are delighted with our exam results released this morning.
“One in five of all our pupils gained at least one A* grade, and four pupils gained a clean sweep of four A* confirming places at Cambridge, Imperial College, the London School of Economics and Oxford.
“Our congratulations go to Helen Amos, Victoria Holley, Sharim Saeed (who also gained an A grade for his Extended Project) and Pujie Yuan.
“A further two pupils gained three grades at A*.
“We also congratulate Anastasia Adams, who is successful in gaining her place to read medicine at Leeds.”
Overall more than 25 per cent of all grades in English Literature, French, Further Mathematics, History, Latin and Physics were of A* level.
The school said it was proud of all its pupils, many of whom have had their university places confirmed today.
The number of pupils completing the Extended Project has increased this year, including an A* for Amelia Mulcahey whose research for her project on oratory included an interview with Neil Kinnock.
Staff said they were also pleased with the AS results, with more than 50 per cent of all the grades in Art, Chinese, Geography, German, History, Latin and Government and Politics being at the top A grade.
In addition, one Year 9 pupil gained A grades in Mathematics and Spanish at AS level, which was Alexander Wardle-Solano.
