NEET 2020 against NEET 2023
What one sitting asked that the other did not — as a share of each paper, because NEET 2020 carries 158 questions and NEET 2023 carries 176. Comparing raw counts across papers of different sizes invents a trend in every row.

Present on one paper and absent from the other
Absent from one sitting is not absent from the syllabus. A chapter carrying one question one year and none the next has told you almost nothing.

74 of 78 chapters moved by less than 1.5 percentage points and are greyed out — at these chapter sizes, a swing of one or two questions is noise, not a signal.
Two sittings are two sittings. Everything above describes what these two papers contained. None of it predicts the next one, and a chapter that fell here is not a chapter to drop — the examiners are not running a trend. The aggregate across every complete paper is the more reliable number.
