JBCN Chembur produces a Cambridge Top in the World Award recipient in its very first IGCSE cohort. Aarjav Jain scores a perfect 100% in Cambridge IGCSE Extended Mathematics — the highest mark in the world.

When a school's first IGCSE cohort includes a Cambridge Top in the World Award winner, it says something important — not just about one exceptional learner, but about the teaching environment that prepared them. JBCN International School, Chembur's Class of 2026 is that cohort, and Aarjav Jain is that learner.

A perfect score of 100% in Extended Mathematics, earning the Cambridge Outstanding Learner Award for Top in the World, is not a milestone that arrives by accident. It is the product of deep subject understanding, precise examination technique, and a school that builds both from the ground up. That JBCN Chembur has produced this in its very first sitting of Cambridge IGCSE examinations is a statement of intent about what this campus is built to achieve.

Aarjav Jain: Cambridge Top in the World in Extended Mathematics

Aarjav Jain | Cambridge IGCSE Extended Mathematics | 100% — Top in the World

The Cambridge Outstanding Learner Award for Top in the World is given by Cambridge Assessment International Education to the candidate who achieves the highest mark in the world in a subject. It is not applied for. It is not voted on. It is awarded based on the published examination results of every student who sat that paper globally.

In Cambridge IGCSE Extended Mathematics 2026, that candidate is Aarjav Jain of JBCN International School, Chembur. A score of 100% in Extended Mathematics — a paper that tests algebraic reasoning, geometry, probability, and calculus-level thinking at the highest level of the Cambridge curriculum — means every mark available, on every question, was earned.

This is the standard of mathematical thinking that leading engineering and science programmes at universities worldwide look for. Aarjav's result places him in an extraordinarily small group of learners globally, and places JBCN Chembur on the map as a school that can develop that level of mathematical ability.

Top Performers: Class of 2026

Four other Chembur learners scored above 90% overall, placing them among the strongest performers in the cohort.

School-Wide Results: JBCN Chembur IGCSE 2026

The individual achievements sit within a school-wide result that is strong by any measure for a first cohort.

For context: The global Cambridge IGCSE A and A* rate varies by subject but typically sits between 20% and 35% for Extended tier papers. JBCN Chembur's 70% A and A* rate in its first cohort is significantly above that benchmark, reflecting the quality of preparation across the whole class.

What This Result Means for a New Campus

JBCN Chembur opened in 2019 and is the newest campus in the JBCN group. This is its first cohort to sit Cambridge IGCSE examinations. A first-cohort result that includes a World Topper, a 100% pass rate, and 70% A and A* grades is not a coincidence — it is the output of a campus that was built with a clear academic philosophy from its first day.

The campus has been independently recognised as No. 1 in India for STEAM Excellence by EducationWorld 2025, and received the Distinguished Performance in Academics award at the Global Education Awards 2026. The IGCSE Class of 2026's results confirm what those recognitions described: a school that integrates Sciences, Technology, Engineering, Arts, and Mathematics not as separate boxes but as one connected approach to learning — and that approach produces results.

Aarjav Jain's perfect score in Extended Mathematics is the clearest single proof point. But the 70% A and A* rate across the whole cohort is the broader story: a school that lifts the standard for every learner, not just the most exceptional ones.

The Road Ahead: IBDP at JBCN Chembur

For the Class of 2026, Cambridge IGCSE is the foundation. The IB Diploma Programme awaits in Grades 11 and 12, and the habits built in IGCSE — mathematical rigour, analytical writing, scientific investigation, and time-managed examination performance — are exactly what the IBDP rewards.

JBCN Chembur runs the full IB continuum: IB PYP from Pre-Nursery, Cambridge IGCSE through Grade 10, and the IB Diploma in Grades 11 and 12. A cohort that produces a World Topper in Mathematics at IGCSE is a cohort that arrives at the IB Diploma with the foundations to achieve exceptional scores. JBCN Parel and Oshiwara both rank in the global top 25 IB schools by results — Chembur is building toward that standard from its first cohort upward.

Congratulations to the Class of 2026

To Aarjav Jain, to Anaisha Bhutani, Rhea Francis, Aimee Mohan, and Avika Ghotikar, and to every learner in JBCN Chembur's Class of 2026 — these results are yours. They reflect two years of consistent work, and they open two more years that can go anywhere.

To the faculty, coordinators, and every member of the Chembur team: a World Topper in the first cohort is the result of what you built. Congratulations.
