Two students from Caleb British International School (CBIS) in Lagos, Nigeria, have achieved the highest scores worldwide in English and Mathematics in the 2025 Cambridge International General Certificate of Secondary Education (IGCSE) examinations. Akota-Chika Serena of the Magodo campus and Tolulope Israel Adekimi of the Lekki campus each received the Outstanding Cambridge Learners Award for their exceptional performance.
Students Credit Teachers and School Support
Reacting to their achievement, both students attributed their success to the unwavering commitment of the school's academic and non-academic staff. They emphasized that the support they received throughout their education was instrumental in their performance. According to them, the school remained dedicated to their academic development, personal well-being, and the goal of producing skilled individuals capable of contributing to national development.
Global Recognition for Nigeria
Dr. Ola Adebogun, Director of Caleb Group of Schools, stated that the students' success has brought international recognition to Nigeria. He noted that the accomplishment reflects both the students' intelligence and the quality of preparation they received. Adebogun highlighted that the school's combination of the Nigerian and British curricula supports its mission to produce "accomplished and ambitious young boys and girls of proven integrity" who are prepared to make meaningful contributions to society.
He further explained that both CBIS Magodo and CBIS Lekki were established to raise confident, happy, and well-rounded children, teaching them that intellectual growth, physical development, and consideration for others are essential for success. "At Caleb Group of Schools, we offer a competitive environment, yet one that actively seeks to promote achievement in every child, and sometimes that achievement is simply by taking part. The opportunities and facilities we offer our children are second to none," Adebogun said.
Investment in Modern Teaching Methods
Adebogun revealed that the school invests heavily in modern teaching methods, including flipped classrooms, artificial intelligence (AI), and language laboratories, to help students develop their abilities and become confident leaders. He also emphasized the importance of recruiting qualified staff and adhering to quality assurance standards set by the government and regulatory bodies. These measures, he said, enable students to perform well in national and international examinations and competitions.
The director linked the school's numerous awards in Nigeria and abroad to its faith-based approach, which combines moral values with quality education in a peaceful learning environment. He stated that every child at the school has the opportunity to fulfill their dreams in a setting that encourages young people to reach their full potential. Additionally, he noted that graduates of the Caleb Group of Schools have distinguished themselves in character and academics across various fields worldwide.
