Rohan Sampath scored 100 per cent in Mathematics, 100 per cent in Physics, 100 per cent in Computer Science and 98 per cent in English, becoming the first student to do it in the history of ISC exams, his school, Dubai Modern High School, said.
The 18-year-old, who has studied at the same school since kindergarten, credited his parents and teachers for his incredible success.
Rohan was the president of the Modern Debating Society at school and represented the UAE at the World School Debating Championships in Scotland, last year.
His father Sampath Srinivasan said his son has always been academically excellent, but that has never been his only focus.
Sampath never went for private coaching classes and says there is no secret formula for success. Outside India, the ISC examinations are taken in schools in Indonesia, Singapore, Bhutan, Yemen and the UAE.
