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

Standard

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

The Making of an IJSO Gold Medalist: Aadish Jain’s Words of Gratitude

Standard

Some achievements are measured by ranks and medals. Others are measured by the depth of understanding, discipline, and intellectual growth developed along the journey.

Aadish Jain’s remarkable journey — from beginning Physics with uncertainty to representing India at the International Junior Science Olympiad (IJSO) 2025 and winning a Gold Medal for the country — is a story of curiosity, perseverance, and genuine conceptual learning.

What makes his testimonial especially meaningful to me is not merely the achievement itself, but the values it reflects: independent thinking, strong intuition, intellectual honesty, and the courage to deeply struggle with difficult ideas instead of relying on shortcuts.

His words beautifully capture the teaching philosophy I have always believed in — that Physics should not merely be memorized, but truly understood.

I am immensely proud of Aadish and deeply grateful to have been a part of his extraordinary journey.


Respected Devansh Sir,

Winning a Gold Medal for India at the International Junior Science Olympiad (IJSO) 2025 after being selected among the six students chosen to represent the country has been one of the proudest achievements of my life. This journey, which began with my qualification in the Indian National Junior Science Olympiad (INJSO) 2025 and continued through the OCSC camp, would not have been possible without your invaluable guidance and mentorship.

As I look back on this entire experience, I realize how deeply your teaching transformed my understanding of Physics and shaped my overall way of thinking.

When I first joined your online classes in June last year, Physics was not particularly my strongest subject. However, as the course progressed, I gradually developed not only conceptual clarity, but also a genuine fascination for the subject. The intuitive manner in which you explained concepts made Physics feel intellectually beautiful rather than intimidating.

What truly makes your teaching extraordinary is your emphasis on genuine understanding instead of superficial problem-solving. While many teachers focus mainly on shortcuts, memorization, and formula-based approaches, you consistently encouraged us to think independently, struggle honestly with problems, and derive equations ourselves. You taught us that developing the correct method and depth of thought is far more important than merely arriving at an answer.

That philosophy had a tremendous impact on me.

Your classes trained me to think analytically, build strong intuition, and approach difficult problems with confidence and patience. Over time, this way of learning became one of the greatest strengths in my Olympiad preparation and played a major role throughout my INJSO, OCSC, and IJSO journey.

Beyond academics, your philosophical insights on discipline, consistency, learning strategy, and personal growth were equally inspiring. They helped me develop a far more mature and focused mindset toward both studies and life.

I sincerely believe that the strong conceptual foundation and scientific temperament I developed under your mentorship became one of the most important reasons behind my success.

Thank you once again, Sir, for your constant encouragement, extraordinary guidance, and for inspiring students to truly understand Physics instead of merely studying it. I will always remain deeply grateful for your support and hope to continue learning from your wisdom in the years to come.

With deepest respect and gratitude,
Aadish Jain

“I Have Not Seen Such High-Quality Lectures Before”: An IIT Delhi Professor’s Remarkable Testimonial

Standard

There are moments in a teacher’s journey that become deeply meaningful — not merely because of praise, but because of the source from which that appreciation comes.

Receiving a heartfelt testimonial from Prof. Saif Khan Mohammed of Indian Institute of Technology Delhi was one such moment for me.

Prof. Saif is not only a distinguished academician from the Department of Electrical Engineering at IIT Delhi, but also someone who himself secured an under-100 rank in IIT-JEE during his student years. His deep understanding of Physics, analytical thinking, and exposure to high-level technical education make his words especially valuable and humbling.

What touched me most was not simply his appreciation of my lectures, but his recognition of the philosophy behind my teaching — beginning from first principles, developing intuition step by step, and helping students gradually build the confidence to solve highly challenging problems, including advanced problems from the legendary book by I. E. Irodov.

As educators, we often strive not merely to teach formulas, but to cultivate curiosity, clarity of thought, and genuine understanding. To know that these efforts resonated with a respected IIT Delhi professor and benefited his daughter deeply is something I will always cherish.

I am sharing his words below with immense gratitude and humility.


Dear Shri Devansh

I am Prof. Saif Khan Mohammed, Dept. Electrical Engineering l.I.T. Delhi. My daughter is enrolled in your online course. I have been personally viewing your physics video lectures and I must say that I have not seen such high quality lectures before. My daughter has seen other online lectures, but none of them are as good as yours. After seeing your lectures she was able to solve difficult problems in Mechanics from the book by I. E. Irodov. The way you start any topic from basics and gradually increase complexity is what makes it easy for students to learn physics with so much ease. I thank you for your great contribution to education and I am sure you will make even greater contribution in the years to come.

Prof. Saif
