Kavya Reddy: 118/120 in JEE Main Chemistry 2025

Kavya Reddy from Hyderabad scored 118 out of 120 in JEE Main Chemistry (April 2025 session), achieving an All India Rank of 89. A self-study student who supplemented with Sri Chaitanya's distance programme, Kavya is unusual among top scorers in that she relied primarily on NCERT and previous year papers rather than standard coaching materials. Her score of 118/120 — dropping just one question on an ambiguous organic mechanism — is a testament to the power of NCERT-first chemistry preparation done with exceptional depth and consistency.

Kavya's Study Philosophy and Daily Routine

Kavya dedicated 3.5 hours daily to chemistry from March 2024, splitting her time as follows: 70 minutes for organic chemistry (mechanism drills and name reactions), 60 minutes for physical chemistry (numerical problems), 60 minutes for inorganic chemistry (NCERT reading, group properties, trends), and 20 minutes for formula and reaction revision from her handwritten notes. "Chemistry is the most NCERT-friendly subject in JEE Main," Kavya explains. "If you read NCERT chemistry carefully — not just the bold text, but every sentence, every footnote, every box — you've covered 80% of what NTA will ask." She read each NCERT chapter a minimum of five times across her preparation, with each reading serving a different purpose: first for overview, second for detail, third for important reactions and facts, fourth for NCERT exemplar problems, fifth for final revision. For the inorganic chemistry strategies that were central to her preparation, she found our Chemistry Score 100 Strategy article aligned closely with her approach.

Her most distinctive habit: maintaining a "reaction journal" — a spiral notebook with one page per name reaction. Each page included: the reaction name, reactants and reagents, product, mechanism (arrow-pushing), key conditions, and any JEE Main previous year question involving this reaction. By exam day, her reaction journal had 87 pages covering every major organic name reaction. She reviewed it every Saturday morning, which kept the reactions fresh without requiring daily deep study.

Physical Chemistry: The Calculation Strategy

Kavya's approach to physical chemistry was methodical: "I treated physical chemistry like mathematics — identify the relevant formula, substitute correctly, compute carefully. There are only about 30 master formulas across all of physical chemistry. If you know all 30 and can apply them in 2 minutes, you will score perfectly in physical chemistry." Her formula mastery technique: write the formula without looking at notes, then verify. She did this for every formula every Sunday, rebuilding muscle memory throughout her preparation. Chapters she found most calculation-dense: Chemical Kinetics, Electrochemistry, Solutions, and Ionic Equilibrium. She solved the complete question bank for each of these chapters from JD Lee's Concise Inorganic Chemistry (for physical chemistry sections) and NCERT exemplar. For previous year numerical problems, she used Disha's JEE Main chemistry archive, solving every numerical from 2015–2025. Practise physical chemistry numericals on our platform to build the calculation speed Kavya credits as critical to her 118/120 score.

Her time on exam: "I attempted chemistry in 35 minutes flat, leaving 25 minutes for error checking. My strategy was: start with inorganic (fastest), then physical (predictable calculations), then organic (sometimes need longer for mechanism questions). I finished organics with 12 minutes left, reviewed my entire paper twice, and corrected one small calculation error in electrochemistry in the final review. That review alone saved 4 marks."

Inorganic Chemistry: Kavya's Memory System

Inorganic chemistry was Kavya's strongest sub-section, and her preparation method is replicable by any student. For each group in the periodic table, she created a "group character card" — a 10×15 cm index card with: key elements, electronic configurations, oxidation states, common compounds, anomalous properties, and 3 JEE-relevant facts. She had 18 such cards (Groups 1–18) plus cards for actinides, lanthanides, and transition metals. These cards went everywhere with her — she reviewed them during lunch, before sleep, and on the bus. "Inorganic chemistry is a memory sport, not a thinking sport," she says. "The student who remembers that KMnO4 oxidises Fe2+ to Fe3+ in acidic medium faster than their competitor is the one who scores higher — there's no calculation to do."

For coordination chemistry — a chapter many students dread — Kavya focused on the 6 key rules: IUPAC nomenclature, isomerism types (geometric, optical, linkage, ionisation), crystal field theory (high spin vs. low spin, colour from d-d transitions), and the spectrochemical series. She created 20 coordination compound flashcards and tested herself on naming and structure identification daily for 3 weeks. Her final coordination chemistry accuracy in mocks: 100%.

Kavya's Advice for JEE Main 2026

"Do not buy ten chemistry books and solve 10% of each. Buy NCERT (mandatory), JD Lee for coordination and inorganic, and one problem book (I used Narendra Awasthi for physical and VK Jaiswal for organic). Go deep in fewer resources. Chemistry is not about the number of problems you solve — it is about how well you understand the 30 reactions and 30 formulas that appear year after year." On organic chemistry specifically: "Learn mechanisms, not products. If you know the SN1 mechanism, you can predict the product for any haloalkane regardless of what specific compound NTA shows you. Product memorisation breaks when NTA shows a new compound; mechanism understanding does not."

Kavya's JEE Advanced 2025 chemistry score: 59/60. She is currently at IIT Hyderabad (Chemical Engineering). Her message to JEE 2026 aspirants: "Chemistry can be your highest-scoring subject if you treat NCERT with the respect it deserves. Read it once like a novel, then 4 more times like a textbook. The marks are there."
