Kirchhoff's Rules: NEET previous year questions

6 questions in ten years of NEET, in 6 of 10 papers. Pattern: Every year. Here is how it is asked and which ideas come back.

Asked in 10 years: 6; about 0.6 per paper
Years asked: 6/10; last asked 2025
Chance of a question next paper: 50%; historical rate, how we compute it
Weighted estimate: 0.5; model; history: 0.6 a paper on average, typically 0–1

Key findings

01
Asked in 6 of 10 papers, 6 questions in all: #133 of 204 topics by ten-year total. It comes back every 1.6 years on average. Last asked in 2025.
02
100% of its questions since 2018 tested an idea never asked before; none repeated an idea from the year before.
03
No idea in this topic has been asked twice: every question tested something new.
04
NEET has asked 6 of the 86 ideas in this topic; 76 have never been asked, directly or indirectly.
05
Mostly asked as figure-based (50%); 50% easy, 0% hard, and down from 0.7 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.
