Most Repeated Questions in NEET Biology, Chemistry and Physics

What are the most repeated questions in NEET? This is one of the most common questions that comes to the minds of the NEET aspirants. As solving NEET questions of previous years is advised for the preparation of this exam, students often wonder, what are the most repeated questions in NEET. To answer this question, it can be said that no, exact questions are not repeated in the NEET question papers. Then what are the most repeated questions in NEET? To know the answer, read this article on Shiksha on most repeated questions in NEET Biology, Chemistry and Physics.

After analysing the NEET question papers of the past few years, it can be said that exact questions are not repeated. However, questions from same concepts, chapters and topics are repeated. Hence, it is important to have conceptual clarity on the high-weightage chapters and topics of NEET.

Hence, if you are expecting to find out the list of most repeated questions in NEET Biology, Chemistry and Physics here, then you will not get it. However, we will provide the most common concepts, chapters and topics of the NEET exam across the subjects or sections, along with free PDF downloads.

Most Repeated Questions in NEET Biology

The Biology section carries the highest weightage in the NEET exam. The subject is further divided into Botany and Zoology, each carrying 45 questions. The total number of questions is 90. Based on the past few years’ NEET analysis, Human Physiology, Genetics and Molecular Biology, Plant Physiology, Ecology & Environment, etc. are the most repeated questions or topics.

Some of the most repeated questions in NEET Biology, or the topics of high weightage, are as follows.

Here are some of the NEET Biology important topics from the chapters with the most repeated questions are as follows:

Genetics and Molecular Biology - Mendelian inheritance, DNA replication, transcription, translation

Human Physiology – Circulatory, Nervous, Endocrine, Reproductive systems

Plant Physiology – Photosynthesis, Respiration, Plant hormones

NEET Difficulty Level and Question Types

NEET 2025 was conducted on May 4, 2025. The toughness level was very high in this year’s exam. Physics was the trickiest section, followed by Chemistry and Biology. Each subject or section carried questions which needed subject knowledge and understanding of the topics. The NEET 2025 questions were not repeated from the past question papers. Some of the questions from Physics and Chemistry were a combination of two to three topics. This also made it a challenge to complete the exam on time, which is three hours.
