Master Mathematics with Confidence
Concept-based maths coaching for Class 8–12 & IIT-JEE by Rahul Sir
Hello Students,
I’m Rahul Banerjee (Rahul Sir), a passionate mathematics educator based in Kolkata with over 15 years of teaching experience. Since 2010, I have been guiding students from Class 8 to Class 12, including IIT-JEE and foundation-level aspirants, helping them build strong concepts and confidence in mathematics.
My teaching philosophy focuses on clarity, logic, and problem-solving, rather than rote learning. I believe that mathematics is not difficult—when explained the right way, it becomes logical, interesting, and even enjoyable. With simple techniques, structured practice, and personalized attention, I help students overcome fear and perform consistently well in exams.
Over the years, my journey in mathematics has been driven by curiosity and excellence, with achievements including the NTSE Scholarship and strong performance in National Mathematics Olympiads. Today, my biggest satisfaction comes from seeing my students grow academically and mentally confident.
If you’re looking for concept-based maths coaching with individual focus, I’d be happy to help you achieve your goals.
