From IJSO Gold to Top JEE Ranks: A Heartfelt Testimonial from Mahroof and Masroor

Posted on by

This testimonial comes from two extraordinary brothers, Mahroof and Masroor, whose journeys reflect the power of deep conceptual learning and disciplined thinking. Under my mentorship, Mahroof went on to win a Gold Medal at the International Junior Science Olympiad (IJSO) and secure AIR 32 in JEE Advanced 2026 and AIR 44 in JEE Main 2026, while Masroor achieved AIR 169 in JEE Advanced 2026 and AIR 58 in JEE Main 2026 after qualifying for the IJSO OCSC. In this heartfelt message, they share how intuition, imagination, and conceptual clarity shaped their success and express their sincere gratitude for the role my teaching played in their academic journey.

Respected Devansh Sir,

We are Mahroof and Masroor, your former students, and we are writing this to express our deepest gratitude for the invaluable role you have played in our academic and personal journeys.

Looking back at our milestones, we realize that the foundation of our success was laid entirely under your mentorship.

With your guidance, we were privileged to achieve milestones we once thought were distant dreams:

  • IJSO Orientation-Cum-Selection Camp (OCSC) Selection
  • Representing India and winning a Gold Medal for the nation at the International Junior Science Olympiad (IJSO)
  • AIR 32 & AIR 169 in JEE Advanced 2026
  • AIR 44 & AIR 58 in JEE Main 2026

While these ranks and medals are a testament to hard work, the true catalyst was the way you taught us to think.

What set your classes apart was a relentless emphasis on INTUITION OVER ROTE MEMORIZATION.

You constantly pushed us to seek the deeper meaning behind every concept, urging us to ask WHY a physical phenomenon occurs before figuring out how to calculate it.

YOUR UNIQUE APPROACH

You taught us the power of imagination. You trained us to visualize complex physical setups and build mental models before touching a pen to paper.

This gift of visualization became our ultimate strength, giving us the confidence to break down completely unfamiliar problems, whether we were competing on an international Olympiad stage or tackling the toughest questions in JEE Advanced.

THE POWER OF CONCEPTUAL CLARITY

In a competitive landscape where many rely on pattern recognition and formula shortcuts, your focus on absolute conceptual clarity became our greatest competitive advantage.

By ensuring our fundamentals were unshakeable, you stripped away the fear of the unknown. When faced with highly complex, multi-concept problems in JEE Advanced and the Olympiads—questions designed to break standard formulas—our strong conceptual foundation allowed us to derive solutions from first principles.

You didn’t just teach us Physics; you gave us the ultimate toolkit to conquer any high-stakes examination.

A MESSAGE TO OUR JUNIORS

To our juniors who are currently learning under Devansh Sir, our biggest advice is to trust his process completely.

In the beginning, focusing deeply on concepts and visualization might feel slower than just memorizing a formula to get a quick answer. But commit to it anyway.

The intuition Sir builds in you is a superpower that compounds over time. When the syllabus expands and the problems get tougher, it is this conceptual depth—not shortcuts—that will carry you through.

Listen to his insights, ask the “WHYS”, and embrace the way he teaches you to think.

SHAPING OUR ACADEMIC FUTURE

Your impact on us goes far beyond these examinations.

You didn’t just prepare us for a test; you genuinely transformed the way we approach learning itself. By instilling a rigorous scientific temperament and a passion for deep inquiry, you have permanently shaped our future academic paths.

The analytical mindset and problem-solving resilience we developed in your classroom are the very tools we will carry forward into our higher education and future careers in science and technology.

A NOTE OF DEEP APPRECIATION

Sir, we feel incredibly fortunate to have been mentored by an educator of your caliber.

Your boundless passion for Physics, your patience, and your genuine investment in our growth have left an indelible mark on our lives. You made a notoriously difficult subject beautiful and enjoyable.

Thank you for your tireless guidance, your unwavering belief in our potential, and for helping us bring pride to the country.

WE WILL ALWAYS REMAIN PROFOUNDLY GRATEFUL TO YOU.

WITH SINCERE RESPECT AND GRATITUDE,

MAHROOF

Why Light Bends Instead of Traveling Straight?

Why Light Bends Instead of Traveling Straight

The Strange Behavior of Light

We usually imagine light traveling in straight lines. Laser beams, sunlight, and torchlight all appear perfectly straight.

But then we observe strange things:

  • a pencil appears bent in water,
  • swimming pools look shallower,
  • diamonds sparkle intensely,
  • roads on hot days look wet.

Why does light bend at all when a straight path seems simpler?

The answer reveals one of the deepest ideas in Physics.

Light Minimizes Time, Not Distance

Most people assume Nature always chooses the shortest path.

But light does something far more surprising:

It chooses the path that takes the least time.

This idea is the key to understanding refraction.

The Lifeguard Analogy

Imagine a lifeguard rescuing a swimmer far away in the water.

Humans run much faster on sand than they swim in water. So the fastest route is usually not a straight line.

A smarter strategy is:

  • run longer on sand,
  • then enter the water later.

The path becomes bent because the goal is to minimize time, not distance.

Light behaves in an astonishingly similar way.

Refraction: Why Light Bends

Light travels extremely fast in air but slows down in materials like water, glass, and diamond.

When light moves from one medium to another, its speed changes. Whenever speed changes, the path bends.

This bending of light is called refraction.

When light enters a slower medium like water, it bends toward the normal because that path reduces the total travel time.

Fermat’s Principle

The French physicist Pierre de Fermat expressed this idea beautifully:

Light travels along the path that takes the least time.

Not the shortest distance.
The least time.

From this single principle, scientists can derive the laws of reflection and refraction.

Everyday Examples of Refraction

Pencil in Water

Light bends as it leaves water and enters air. Your brain assumes light traveled straight, so the pencil appears bent.

Diamonds

Diamonds slow light dramatically. Light repeatedly bends and reflects inside them, creating intense sparkle and shimmering colors.

Mirages

On hot roads, layers of hot air change the speed of light gradually. Light curves upward, creating the illusion of water on the road.

A Beautiful Lesson from Nature

Nature often behaves differently from human intuition.

We think in terms of:

  • straight lines,
  • shortest distance,
  • direct paths.

But Nature often optimizes something deeper:

  • efficiency,
  • time,
  • and elegant physical laws.

Light bends because the bent path is actually faster.

That is one of the most beautiful ideas in Physics.

One-Line Takeaway

Light bends because Nature cares more about time than straightness.
