At the high school, 86% of students entered for two or more A Level subjects achieved the all important Level 3 qualification for schools in Wales.
In art, biology, business studies, chemistry, English, fine art, French, geography, health and social care, history, IT, law, mathematics, music and performing arts, the pass rate was 100%.
Headteacher Tony Davidson said: “In addition to their A Level passes, 100% of our students entered for the WBQ (Welsh Baccalaureate Qualification) achieved the full award.
“This is the first time we have offered the Baccalaureate to such a large proportion of the post 16 cohort of students and I am delighted with our progress this year.
“These well deserved results will enable the majority of our students to attend their university of first choice.
“Our success reflects the hard work and dedication of the students and staff and the continued support of parents. I congratulate everyone on a job well done.”
Students who achieved outstanding results include Adam Beales (three A grades in chemistry, mathematics and physics) and Mia Bartlett (A* in sociology, two A grades in mathematics and art and design).
