Mission Report: Nine Years Before the Camera
Before I launched DBS Classes on YouTube, I had already spent nearly nine years in the trenches of tutoring. Over that near-decade, I guided roughly 200 students. My classroom sizes varied significantly — crowded local school environments with 30 to 40 eager pupils, intimate offline coaching centers with batches of 20 to 25, one-on-one personal coaching mentorships, and online groups for NRI and international students.
Throughout that journey, I kept encountering the same structural failure: the conventional education system’s obsession with rote memorization. I watched students spend hours memorizing formulas to pass standardized examinations without ever understanding why those equations worked or what they represented in the physical universe. They could solve for variables, but they could not connect the math on the page to the real world.
That pattern is what pushed me to hit record.
Mission Report: Launch Parameters
I founded DBS Classes on October 31, 2022. The abbreviation stands for “Dhaatu Bhaiyaa’s Classes” — where “Dhaatu” is my nickname among close companions, and “Bhaiyaa” is the Hindi honorific for big brother, which is how my students affectionately addressed me. I established the platform on a non-negotiable axiom:
"Education Is Not Free BUT KNOWLEDGE IS FREE"
...and must be shared with "ZERO TERMS AND CONDITIONS"
I believed — and still believe — that premium, high-quality, concept-first education should not be locked behind paywalls, sign-up forms, or marketing funnels. It had to be freely accessible to anyone, anywhere, with zero caveats.
Mission Report: Bridging Theory and Observation
With that philosophical compass guiding the channel, my target was straightforward: replace mechanical compliance with genuine scientific intuition. I structured the curriculum around three main pillars:
- Make Physics and Mathematics highly intuitive: Demystify equations by explaining the geometrical and logical origins of concepts like trigonometry and dimensional analysis.
- Teach using first-principles thinking: Instead of starting with pre-derived equations, start with the most basic, undeniable facts of nature and build upwards.
- Bridge the gap between abstract equations and real-life observations: Connect the abstract symbols in textbook mechanics to concrete occurrences — how the wheels of a city bus rotate, why a spinning cricket ball curves through the air, how kinematics play out on a football field.
My very first upload, titled Introduction: Unlocking the World of Mathematics and Physics, was an open invitation to look at science through this lens. Over the first few months, I poured my energy into constructing highly visual, rigorous, and conceptual lectures covering fundamentals like dimensional analysis, trigonometry, and basic kinematics.
I did not just want to help students pass exams. I wanted to build a repository of free, high-fidelity lectures that treated students not as passive test-takers, but as active, curious explorers of physical reality.
Mission Report: Status and Continuation
Twenty video logs made it to the archive before consistency broke down — a failure I document separately and without excuse. But the why behind DBS Classes has not changed. The channel was never about views or algorithms. It was about giving every student the kind of explanation I wished I had received when I was sitting in a classroom, memorizing formulas I did not understand.
