How did this team from IITM quietly build the world's largest edtech platform? | BP2B S1 Ep. 25

In this explosive episode, we sit down with Professor Andrew Thangaraj from IIT Madras—the mastermind behind NPTEL and the IIT Madras BS Program — who is literally revolutionising how millions of students access world-class education. Professor Andrew Thangaraj reveals: ✅ Shannon's "magic" formula that powers your phone, camera, and every digital device ✅ How NPTEL started BEFORE YouTube and MOOCs even existed (visionary!) ✅ The untold story of how IIT Madras has built something that reaches 980,000 students in a single semester - yes, that’s the number of students taking proctored exams in one semester. But here's where it gets wild - their BS program is producing GATE toppers from students who started with "literally zero background." One student was an AIIMS doctor who realized medicine wasn't for him. Now he's GATE DA Rank 1 through IIT Madras BS program. Professor Andrew explains how they cracked the code on filtering students throughout the program instead of just at the entrance. Controversial? Maybe. Effective? The results speak for themselves. This video is a roadmap to accessing world-class education regardless of your background or JEE rank! 💡 Perfect for: - High school students confused about career options - Parents worried about their child’s future - Anyone who thinks quality education is only for the privileged - Students looking for alternatives to traditional engineering WATCH NOW and discover how education is being democratised in India!

WHAT IT’S REALLY ABOUT

How IIT Madras scaled NPTEL into degrees and national impact

  1. NPTEL began in 2000 by recording IIT classroom lectures and distributing them free—well before YouTube and the MOOC wave—to broaden access to IIT-level teaching nationwide.
  2. NPTEL’s major inflection point was adding certification via proctored, in-person exams (from 2014), creating employer- and college-trusted credentials that later fit naturally into the government’s SWAYAM portal.
  3. SWAYAM enabled scalable credit transfer across institutions, reducing the friction of bilateral MOUs and helping mainstream online learning in India at a national level.
  4. IIT Madras leveraged NPTEL’s operational know-how to launch low-cost, large-scale BS programs (Data Science and Electronic Systems) using a “wide entry, tough progression” model: qualifier → foundation → diploma → degree.
  5. The BS programs aim to convert high-potential learners—often excluded by JEE coaching economics—into employable graduates, with strong financial support and early skills-first learning validated by projects and vivas.

IDEAS WORTH REMEMBERING

5 ideas

NPTEL succeeded early because it solved a faculty-quality distribution problem.

Recording IIT lectures gave colleges and self-learners nationwide “a peep into IIT classes,” addressing uneven teaching capacity without requiring physical mobility.

Proctored exams were the trust-engine that made online credentials mainstream in India.

IITM rejected purely online exams for certification and instead used center-based invigilated tests, aligning with how Indian institutions validate performance and enabling reputation-building at scale.

Scale comes from repeatable operations, not just great content.

Running LMS workflows, payments, question paper setting, exam logistics, and evaluation processes (plus in-house execution) created the backbone that later made BS degrees feasible.

SWAYAM’s real breakthrough is administrative interoperability (credit transfer).

By standardizing course + certification under a ministry-backed portal, SWAYAM reduces the need for one-off inter-university MOUs, making credit recognition practical at national scale.

IITM’s BS model flips the traditional IIT approach: admit wider, filter through learning.

Instead of extreme upfront selection (like JEE), the program uses staged progression—qualifier, foundation, diploma—so motivated learners can prove capability over time and exit with meaningful credentials.

So whatever we can scale, we should scale.

This is before YouTube and all that.

Andrew Thangaraj

We have taken them from zero, literally, and given them every single thing that they know.

Andrew Thangaraj

We wanted to create something which would have a chance of building up a reputation… it has to be followed by a proctored exam.

This year, GATE DA paper, Rank 1, Rank 7, and Rank 10 are BS students… First rank… is an AIIMS doctor.
