Pupils at Sir John Leman High School were hailed after one of the best years on record for the Beccles school.
Headteacher Michael Taylor said: "This year’s A Level and GCSE results have seen a return to traditional student exams, following two years of grades being based on school assessments.
"So I am really impressed with the out comes and the effort teachers and students have put in together.
"We have all worked so hard collectively and the outcomes, in one of our best years statistically, shows that.
"We have lots of smiley faces here today and that is testament to my staff and the students for their application."
Sir John Leman had a pass rate of 87pc for English and a pass rate of 75pc for maths.
There were a number of high achieving students celebrating on results day.
Among them was Jack Fisher, who achieved a remarkable seven grade 9s in subjects including combined science, English language, maths, music, religious studies, Latin and computer science.
The 16-year-old said: "I am a combination of shocked and relieved.
"I'm glad that all the hard work has paid off.
"I look forward to beginning to study my A Levels here at the Leman in music, maths, further maths and computer science."
His mother Christina Fisher added: "It's phenomenal. I am so proud of my son and glad he has got the outcome he dreamed of because he worked so hard."
Another student who was thrilled having done exceptionally well was Elijah Britton who achieved six grade 9s, two grade 8s and two grade 7s.
Ms Britton said: "I am not crying tonight which is a relief, I am just pleased the late nights revising have proved worthwhile.
"I am staying on here at the Leman to study biology, religious studies and chemistry."
Teacher Ms Nabarro said: "I am just so proud of Elijah, she has truly smashed it, and we are happy she has chosen to stay with us to study her A Levels"
