LIPI Analytics · Topical Analysis based on PYQs

Which topics actually carry the exam.

Every Class 11 and 12 chapter, subject by subject, traced back only to prerequisites confirmed by reading actual chapter content — plus real board, NEET and JEE frequency data per topic.

Plain Core/Moderate/Low text = real board-exam marks (Class 10 and 12 only, the only classes with a board exam). Class 11 has no board exam, so those anchors default to "N/A in 12th Board" and a small faded dot. A blue ring and blue "NEET Core/Moderate/Low" text means real NEET frequency data (medical entrance). A red ring and red "JEE Core/Moderate/Low" text means real JEE Main+Advanced frequency data (engineering entrance). A purple ring means both are present. Physics and Chemistry carry both NEET and JEE data; Maths carries JEE only (NEET doesn't test Maths); Biology carries NEET only (JEE doesn't test Biology). NEET figures cover 2021–2026 (6 real exam years); JEE figures cover 2022–2026 (5 real exam years) — the two windows are not the same length. Hover any dot for the actual chapter title. A dashed badge means the real prerequisite is another chapter in the same class, not an earlier one.
