That's what Trinity Catholic College student Kya Lamarra managed to achieve in his Higher School Certificate (HSC).

He was already on track to get a high score given the fact he had already gotten full marks in advanced mathematics last year.

Kya said he felt a bit of pressure heading into the exams, but a lot of it was relieved as he received an early admission into university.

He wants to work in the field of research in the future and he has given himself the best chance to do so as he will be studying a Bachelor of science (advanced) (honours) degree at the Australian National University.

His father Michael Lamarra said it was an incredible achievement.

"I always thought he was bright," Mr Lamarra said.

"He has had a fantastic gift at mathematics since he was young.

"The school identified it and put him in an excelled course."

Kya's aim was to beat his older brother's score, but it ended in a tie.

Another high achiever was Alexander Dawes whose ATAR was 90.05.

Trinity Catholic College principal Gaye McManus couldn't be prouder of the students' efforts, especially given the difficult year it had been.

"I want to congratulate to all those who achieved strong results in their recent HSC," Ms McManus said.

"We are incredibly proud of those students who have exceeded their own expectations with excellent results in their passion subjects too.

"Every student has been able to pursue their chosen pathway whether it be through university, TAFE, full-time work or an apprenticeship."

The high results were spread across almost every subject taught at the school.

COVID-19 made things tough for the students, but most pulled through with flying colours.
