Ranabir Das

Director & Co-Founder

Dear Learners, Partners, and Supporters, Welcome to BookmarksEducare - Where Education Touches Excellence As the Director of this ambitious venture, I'm thrilled to introduce you to a platform born out of a deep belief: that quality education should be accessible, engaging, and adaptable to the needs of the modern world. In an era defined by rapid change, we understand that learning can no longer be confined to classrooms or rigid schedules. That's why we've built a digital learning ecosystem that empowers individuals to take control of their education anytime, anywhere. At BookmarksEducare we're not just delivering content we're building experiences. Our courses are designed by passionate educators and industry professionals, ensuring each module is practical, relevant, and aligned with the skills today's learners need to thrive. Whether you're a student aiming to supplement your education, a professional seeking new opportunities, or a lifelong learner hungry for knowledge, we're here to support your journey. This is just the beginning. As we grow, we remain committed to listening, learning, and evolving. With technology as our foundation and learners at our core, we are here to transform education into something more inclusive, personalized, and powerful. Thank you for being part of our journey. Warm regards, Ranabir Das Director & Co-Founder BookmarksEducare

Ms. Sampa Sarkar

Director

Dear Students, Parents, and Educators, As I pen down these few lines, my heart feels both full and grateful. Education, to me, has always been more than books and lessons — it is about nurturing young minds with love, patience, and care, just as a mother tends to her child's first steps. Having spent years among little ones, I've learned that every child blooms in their own time, with the right warmth and encouragement. Our online platform is born from that same belief — to reach every learner with compassion, to hold their hand even from afar, and to ensure that no dream goes unheard or unsupported. In this ever-changing world, technology has become a bridge that connects hearts and minds beyond classrooms. Through this institute, we aspire to bring the same comfort, trust, and personalized care that one feels in a nurturing home environment. To all my dear students — learn with curiosity, not fear. To parents — thank you for trusting us with your most precious gift. And to my team — continue to teach not just with skill, but with heart. Let us grow together, one lesson, one smile, and one success at a time. Warm Regards Ms. Sampa Sarkar Director, BookmarksEducare.
