Fifty Reddam House Durbanville pupils sat for advanced subsidiary (AS) level exams in November last year and the school scored a 92% pass rate with 125 subject distinctions.
And 22 pupils sat for advanced (A) level exams and scored an aggregate average of 77%.
The Cambridge International AS and A levels are part of the dual curriculum offered by the school.
The AS level is equivalent to matric and the A level is more suitable for pupils who want to increase their chances of getting accepted into a university, according to Monica Dunk, the head of administration at Reddam House Durbanville.
Le Roux Lategan, who wrote three A-level exams, scored 94% in physics, 92% in maths and 91% in chemistry.
Le Roux’s overall aggregate average stood at 92% for the A-level exams and 90% when combined with his AS-level English language mark.
He said he approached the exams by maintaining a balanced lifestyle that included studying hard while making time for his loved ones, karate training and the gym.
Minkyum Kim, who obtained an overall average of 92.6% in the AS-level exams said: “I think the most important thing to remember for AS and A level exams is that just understanding the material is not enough. It is important to work through many problems (generally) so that you know how to apply your knowledge in the exam questions.”
