About the Educator
Sayantani Roy founded brainRattle with a singular conviction: memorising a textbook is not the same as understanding a subject — and neither guarantees marks. As a Senior Secondary CBSE Faculty and an active Board Evaluator, she teaches students exactly what examiners look for, how marking schemes reward precision, and how to convert conceptual clarity into flawless board answers.
Every program is engineered around conceptual depth, analytical thinking, and disciplined answer writing — so students don't just complete the syllabus, they command it.
To help every student build unwavering confidence, think critically, score excellent marks, develop deep analytical skills, and lay a rock-solid foundation for higher education.
Active CBSE Board Evaluator — teaching from the examiner's side of the desk.
