Niall O’Donovan (15) from Sligo town became the first pupil in many years to achieve a perfect result in the Junior Cert in Summerhill College.
Principal Paul Keogh described Niall as a “very conscientious, modest young man. It was an extraordinary achievement. He’s absolutely over the moon.”
Niall modestly said he felt he "did fairly well" after getting a whopping 12 As in his Junior Cert.
He was one of only four students in the State to achieve the highest marks possible.
"It was a huge surprise. I wasn't expecting it at all," he told Independent.ie
When it came to studying for the exams, Niall said he kept a balance between school and sport.
"I did a bit [of study] after school but I didn't kill myself. I'm in the local swimming club so I do about eight hours of swimming there each week."Transition
Niall's favourite subjects in school are maths, science and technical graphics. He's still mulling over his future after secondary school but hopes to study physics or maths in college.
At the moment, the 15-year-old is enjoying all the non-academic activities of transition year.
"Transition year is great because you get to do a lot of different projects. I'm really looking forward to getting my mini company going and making a profit. We're still in the brainstorming stages at the moment but it should be a lot of fun," he said.
His father Diarmiud said he was "extremely proud" of his son.
"I always knew he was going to do well. He kept it ticking over throughout the year. He didn't cram everything in at the end," he said.
"I think Niall was more nervous last night ahead of the results than he was during the exams."
