St John's College's top pupil, who bagged 10 distinctions, was not home to celebrate his achievement with his peers.
James Geldenhuys is currently in the United Kingdom auditioning for the Royal Academy of Music in London and for the Birmingham Conservatoire.
The flute player is pursuing his musical dream.
In a message, Geldenhuys said: "I'm looking forward to my new life, but I will miss the school, my teachers and all the friends I made. I cannot thank St John's enough for all it [has] given me."
His fellow pupils, Benjamin Kahamovitz and Tariq Seedat scooped nine distinctions each.
Andrew Raney and Gregory Basslian obtained eight distinctions each.
Stefano Osato, 18, who got seven distinctions in Drama, Visual Art, Mathematics, History, Physical Science, Life Orientation, English and Afrikaans said he was happy with his results.
Osato felt that he could have obtained nine distinctions if he hadn't missed Advanced Programme Mathematics by a small margin.
"You get what you put in. I don't think I put in as much as I should have, but the rest I am quite happy with," he said.
Osato is heading to Wits University to study Actuarial Science.
He said he started preparing for his examinations early.
