And those achievements were extraordinary! Just consider Phuong Anh Le, for example. Phuong Anh attained the highest mathematics result in the world in 2019, when she presented for her IGCSE Mathematics, whilst only a Year 10 student. Since then, she has continued to excel. This summer Cambridge International rewarded her efforts and all-round academic brilliance with a further nine IGCSE subject grades, all at A* level.
