AP Calculus BC and AP Statistics 5/5: Om's Double Perfect Score

Om earned a perfect 5 on both AP Calculus BC and AP Statistics in the same year, two college-level exams that test very different skills. His Cuemath tutor Kayalal has taught him since Grade 6, a six-year foundation that made the double possible.

Om Harshadh, Grade 11 AP Calculus BC and AP Statistics, Score 5, Cuemath US

Faced with a problem that looks complicated, many students move on and plan to come back to it later. Om Harshadh settles in and solves it right then.

That instinct paid off twice over. Om, a Grade 11 student in the US, earned a perfect 5 out of 5 on both the AP Calculus BC and AP Statistics exams in the same year. His Cuemath tutor, Kayalal Pachaiyappa, has taught him since Grade 6, a six-year run of weekly online math tutoring.

Sitting two college-level math exams in a single year is a heavy load, and these two pull in different directions. AP Calculus BC moves fast through two semesters of college calculus, while AP Statistics trades formulas for reasoning about data and uncertainty. Doing well in both at once asks for real range, and the discipline to go deep in one subject without losing your grip on the other, sustained across a full year.

"Even during their summer vacation, Om Harshadh did not stop his classes. His focus and persistence were systematic. Building knowledge and connecting each topic with a fact was interesting with Harshadh. Looking at complicated questions, Om Harshadh would never skip the question and move on to the next question. Instead, he would start working on the question and solve the mathematical problems with ease.

Harshadh's consistent learning gives him good learning outcomes. It's great applause to Om Harshadh on reaching high in his efforts. Scoring 5 / 5 in both AP Calculus and AP Statistics adds pride and happiness to his parents and me. It was a good journey with Om Harshadh since grade 6, learning and chit chats with a professional positive approach."

What made the difference was how Om worked and how Kayalal taught. She built his understanding concept by concept, tying each new idea back to something he already knew, so the material held together rather than piling up. He met hard questions head-on instead of setting them aside, and he kept his sessions going even through the summer, so his momentum never broke. Over six years, that steady, connected way of learning turned two demanding syllabuses into material he genuinely understood.

"Our journey with Cuemath started when my son, Om Harshadh, was in 6th grade. Looking back today, enrolling him was one of the best academic decisions we ever made. What started as support for school math slowly became his greatest strength. Cuemath didn't just teach him how to solve problems — it taught him how to think logically, to be curious, and to never be afraid of a tough question. That strong conceptual foundation built over the years is what made all the difference.

I am incredibly proud to share that Om Harshadh, now in junior high, has scored a perfect 5 out of 5 in both AP Statistics and AP Calculus. At the heart of this 6-year journey is his amazing teacher, Ms. Kayalal. She has been teaching him since 6th grade and has been so much more than a tutor — she has been his mentor, guide, and biggest cheerleader. Her patience, dedication, and incredible clarity in explaining the most complex topics is truly remarkable. She understood Om's passion for technology and problem-solving and nurtured it beautifully. Her consistent belief in him gave him the confidence to aim high.

Thank you, Cuemath, and a heartfelt thank you to Ms. Kayalal for shaping Om's academic journey and for being a part of his success story. We are forever grateful!"

AP Calculus BC covers about two semesters of college calculus, from limits and derivatives through integrals and infinite series. AP Statistics is a college-level, algebra-based introduction to statistics: exploring data, working with probability, and drawing conclusions from samples. Both are scored from 1 to 5, and a 5 is the top. Reaching it in two college-level math courses in one year is rare, and Om is not the only Cuemath student to do it, another earned a perfect 5 on AP Statistics too.

Om is in Grade 11, and he already meets an unfamiliar problem the way a mathematician does: he stays with it, connects it to what he knows, and works it through. That habit, built over six years rather than crammed for one exam, is what being MathFit really means, deep understanding, steady confidence, and the persistence to stay with a hard problem until it opens up. Foundations like his are built early and compound quietly, one connected idea at a time.
