Some students achieve extraordinary academic milestones. A few, however, achieve something even more meaningful — they develop the ability to think deeply, understand fundamentally, and approach learning with genuine intellectual curiosity.

Aditya Pericherla’s journey is one such story.

From studying Physics under my guidance for nearly four years to earning admission to University of California, Berkeley, securing perfect 5/5 scores in all four AP Physics examinations, and achieving Distinction twice in the prestigious Sir Isaac Newton (SIN) Exam conducted by University of Waterloo, Aditya’s accomplishments reflect not only academic excellence, but also remarkable conceptual maturity.

What makes his testimonial especially meaningful to me is the way it captures the philosophy with which I have always tried to teach Physics — not as a subject of memorization and formulas, but as a discipline rooted in imagination, intuition, visualization, and first-principles thinking.

His words beautifully reaffirm a belief I hold deeply: when students truly understand concepts instead of mechanically learning them, confidence, creativity, and excellence follow naturally.

I feel immensely proud of Aditya’s journey and grateful to have been part of these formative years of his life.

Earning admission to University of California, Berkeley, securing 5/5 scores in all four AP Physics examinations, and achieving Distinction twice in the Sir Isaac Newton (SIN) Exam conducted by University of Waterloo are milestones that I am deeply proud of. But behind each of these achievements lies a teacher whose mentorship fundamentally shaped the way I think and learn — Mr. Devansh Mittal.

I studied Physics under him for nearly four years, and during that journey, I experienced a style of teaching that was profoundly different from conventional academic instruction.

Most students are taught Physics as a subject driven by formulas, memorization, and repetitive problem-solving. Mr. Mittal approached it differently. In his classes, Physics felt alive. Every concept carried intuition, imagination, and meaning. He consistently emphasized that true understanding begins when a student can mentally visualize a phenomenon rather than merely manipulate equations on paper.

That philosophy changed the way I approached science.

Inspired by the ideas of Albert Einstein, he often highlighted the importance of imagination and intuition in learning Physics. Instead of encouraging mechanical learning, he trained us to think deeply about why things happen the way they do. Whether we were studying Mechanics, Thermodynamics, Waves & Oscillations, Electrodynamics, Geometrical Optics, Wave Optics, or Modern Physics, his teaching always focused on building concepts from first principles.

What made his classes especially impactful was the extraordinary clarity with which he explained difficult ideas. Complex topics that initially seemed abstract or intimidating gradually became intuitive through his method of teaching. He had an exceptional ability to identify conceptual gaps and patiently guide students toward genuine understanding.

Over time, I realized that his classes were not simply preparing me for examinations — they were developing my analytical thinking itself.

The conceptual depth and confidence I gained under his mentorship played a crucial role in my academic achievements, particularly in highly conceptual examinations such as the AP Physics exams and the SIN exam, both of which demand much more than memorized techniques. His approach cultivated the kind of problem-solving ability that comes from deep understanding rather than surface-level preparation.

Beyond academics, however, what truly distinguished him as a mentor was the sincerity and honesty with which he cared for his students.

He remained consistently involved in our progress throughout the years, regularly communicating with our parents and providing detailed feedback regarding our strengths, weaknesses, consistency, and improvement. That level of personal attention created a strong sense of discipline and accountability that motivated me to continuously push myself further.

Very few teachers invest themselves so genuinely in the long-term development of their students. Mr. Mittal always did.

Looking back today, I feel extremely fortunate to have learned under someone who not only taught Physics brilliantly, but also taught us how to think with clarity, curiosity, and confidence.

Mr. Devansh Mittal is far more than an excellent Physics teacher. He is a mentor who leaves a lasting intellectual impact on his students — someone who inspires them to move beyond rote learning and truly appreciate the beauty of scientific thought.

I will always remain grateful for his guidance and mentorship throughout these formative years of my life.
