A 12-year-old boy from Scunthorpe is believed to be the youngest pupil to receive an A-level result on Thursday.
After being taught for just two hours a week at John Leggott sixth form college Terence Linnell took the maths exams at the age of 11 and gained A grades.
He said it felt odd to sit the core mathematics and mechanics papers so early but he found the subject easy and had understood "most" of the course.
"I just feel, 'Why me?', but I'm very happy about it," he said.
Terence, who gained an A* in his maths GCSE at the age of 10, studies other subjects alongside pupils his own age at Brumby Engineering College.
He said he usually had to miss one of his English lessons to attend the sixth form college but added: "I was able to catch up though."
Now he is hoping to pursue a career designing computer games or follow in his father Steven's footsteps and work in engineering.
"After I've finished at school, I will probably go to university and then I might want to be a scientist, or design computer games," he said.
His mother, Hui-Yu, who is originally from China, said she was very proud of her son who she described as a "normal" child with a very good memory.
"He's always been very good at maths," she said. "Even in infant school he had a very good memory."
