Hi, I’m Dr. Ritukar Chadha, founder of the Landmark Institute (New Delhi) and creator of Nayi Rahen. With a PhD in Mathematics and nearly three decades of teaching experience, I have had the privilege of guiding thousands of students — from high school learners to university graduates — toward academic excellence. Over the years, I have taught at several Guru Gobind Singh Indraprastha University (GGSIPU)-affiliated colleges as faculty, where I built my reputation for simplifying complex mathematical concepts and inspiring confidence in learners.

Our Mission

Mathematics is not just a subject — it’s a way of thinking. My mission is to help students overcome fear, build clarity, and unlock their true potential, whether for IB, SAT, or higher-level university studies.

Our Vision

My vision is to combine traditional academic rigor with modern learning needs, creating platforms where students receive the best guidance to succeed in India and abroad.
