One of the most common questions in the minds of NEET aspirants is: What are the most repeated questions in NEET? Students often practice previous years’ papers to improve accuracy and confidence, but they also wonder whether the exact questions repeat in the NEET exam. After analysing past NEET papers, it is clear that the exact questions are not repeated, but questions based on the same concepts, chapters and high-weightage topics appear frequently every year.
This makes it extremely important for students to identify the chapters that carry maximum weightage and the concepts that NTA repeatedly tests. In this article, we break down the most repeated questions/topics in NEET Biology, Chemistry and Physics, along with chapter-wise weightage, question trends, and preparation tips.
Why Understanding Repeated Topics Matters in NEET?
Studying the most repeated concepts helps aspirants:
-
Understand which chapters are prioritised by NTA
-
Improve accuracy in high-scoring areas
-
Reduce preparation time by focusing on important topics
-
Strengthen conceptual clarity in topics that appear every year
-
Build confidence in scoring well in all three subjects
Let’s explore subject-wise trends.
