what the exams actually test
Chapter weightage, from real papers — not opinion.
Every count below comes from an actual verified NTA question in our bank — NEET 2022–2025 and every shift of JEE Main 2024–2025. (Text-only questions; diagram-based ones are excluded, which slightly undercounts circuit- and graph-heavy chapters.)
