We moved from Singapore and chose Prime because of the Cambridge results. Within a term, our daughter was settled, challenged and genuinely happy. The named form tutor made all the difference — she was known before she walked through the door.
My son sat 9 IGCSEs and achieved 7 A* and 2 A. His A Level offer from LSE came six months later. The university counsellor at Prime knew his application as well as he did — and had started working with him since Year 11.
The bilingual programme at Sintra was the reason we chose Prime. Our daughter entered Reception knowing only French and English. By Year 4, she was genuinely fluent in Portuguese. It happened naturally, joyfully — and at a fee level we hadn't expected.
