Elasticity: NEET previous year questions

7 questions in ten years of NEET, in 7 of 10 papers. Pattern: Every year. Here is how it is asked and which ideas come back.

Asked in 10 years: 7; about 0.7 per paper
Years asked: 7/10; last asked 2024
Chance of a question next paper: 50%; historical rate, how we compute it
Weighted estimate: 0.5; model; history: 0.7 a paper on average, typically 0–1

Key findings

01
Asked in 7 of 10 papers, 7 questions in all: #125 of 204 topics by ten-year total. It comes back every 1.2 years on average. Last asked in 2024.
02
83% of its questions since 2018 tested an idea never asked before; none repeated an idea from the year before.
03
The most repeated idea is Young's Modulus Calculation, asked 2 times (2018, 2020), usually as “numerical”.
04
NEET has asked 6 of the 89 ideas in this topic; 80 have never been asked, directly or indirectly.
05
Mostly asked as one-line MCQ (57%); 57% easy, 0% hard, and down from 0.8 to 0.3 questions a paper since 2024.

New idea, or one asked before?

Each column is a paper. Blue questions tested an idea NEET had not asked before; navy ones went back to an idea from an earlier paper. 2017 is the first paper, so everything in it counts as new.
