Most Repeated Questions in NEET Exam would help students revise the concepts, formulas, reactions, diagrams and NCERT facts that have been asked in previous years. But there is no guarantee that the same question will be repeated. The National Eligibility cum Entrance Test (NEET UG) could ask about the same concept with different values, statements, diagrams or answers.

For NEET 2027 preparation, the students should solve the previous year questions (PYQs) along with NCERT books, chapter-wise MCQs and mock tests. Going through NEET repeated topics chapter-wise weightage could help the candidates in recognising the frequently repeated concepts. The students should prepare using the repeated questions for better understanding and not for NEET exam prediction.
The exact questions asked in the previous year NEET exams may not get repeated again. But then the concepts from high-weightage NEET chapters, equations, chemical reactions, diagrams, and facts used in the previous questions can make a base for the NEET 2027 exam questions.
A physics question that was set on a certain equation can be given different figures to work on, whereas a biology question can come out from the same NCERT fact but in a new statement or assertion and reason format. Questions in Chemistry might be on the same reaction, equation, and numerical but with different options.

Biology is seen as the subject which contains the maximum number of NCERT-based facts and concepts. Biology accounts for 90 out of 180 questions in NEET, so it is necessary that students prepare themselves well by going through the prescribed NCERT books. But the repetition of concepts changes every year.
Subject | Common repetition pattern | What to revise |
Biology | NCERT facts, examples, diagrams and biological processes | NCERT lines, tables, diagrams and chapter-wise PYQs |
Chemistry | Inorganic facts, reaction patterns and Physical Chemistry numericals | NCERT facts, reaction mechanisms, equations and numerical methods |
Physics | Familiar formulas and concepts tested with changed values or applications | Formulae, derivations, numerical problems and conceptual applications |
Biology is likely to be an easy scoring subject for the students who have a good grasp of the concepts given in NCERT textbooks. Similarly, Physics and Chemistry are also likely to be scoring for students who understand the fundamentals and practice questions on a regular basis.
Careers360 analysis of the NEET 2026 Biology question paper showed that there were a number of concepts which were quite similar to the concepts tested in past years. This paper included NCERT-based, statement-based, conceptual and sequence-based questions.
Subject | Concepts or question patterns to revise |
Biology | Sickle-cell anaemia, lac operon, RuBisCO, sacred groves and in-situ conservation, logistic growth, cell cycle phases and population interactions |
Chemistry | Revise recurring NCERT facts, reaction patterns and numerical methods using the official question paper and answer solutions |
Physics | Revise familiar formula-based and conceptual numerical questions using the official question paper and answer solutions |
NCERT-based questions were another type of questions present in the Biology paper analysis. These were questions related to facts and examples from NCERT, but statements were slightly changed to test the concepts. Similarity of a question to a previous year's question does not always imply repetition of the same question.

Each year, NEET 2027 comprises a mix of questions from Physics, Chemistry, and Biology based on concepts, calculations, and facts. Biology predominantly consists of direct NCERT-based MCQs. Chemistry has theory as well as numerical problems. Physics consists of more important NEET physics formulas and calculation-based questions. A large number of questions, particularly from key topics, are repeated in different forms across years. Check the 100 most important NEET biology questions to score 330+ marks for better practice and preparation.
The data about the most repeated concept from each chapter is given below. These most repeated concepts are based on Physics previous year paper analysis:

There are many benefits in practising the most repeated questions in NEET preparation:
Helps to identify high-weightage chapters which repeat themselves in the examination
Improves conceptual understanding as they are based on important topics
Helps in knowing the pattern and difficulty level of NEET questions
Enhances speed and accuracy in attempting MCQs
Improves confidence before the examination
Many NEET toppers suggest students solve NEET PYQs, as around 60-70% of questions have concepts that are the same as previous years. Therefore, analysing repeated questions is one of the most effective strategies for NEET 2027 preparation.
First, read the corresponding NCERT concept to develop a proper understanding before working on the questions.
Work on repeated concept questions chapter-wise to know the repeated topics and the pattern of questions.
Practice PYQs once you complete each concept to know how concepts are asked in NEET.
Analyse wrong answers and revise those concepts.
Keep revising the frequently repeated concepts for better recall and practice.
Do not solely rely on the repeated questions, as NEET may ask for new applications of the old concepts.

Yes, solving NEET previous year questions helps students understand important topics, exam patterns, and frequently tested concepts.
Biology generally has the most repeated concepts because many questions are directly based on NCERT textbooks.
No. Repeated questions are useful for revision and practice, but students must also study NCERT, complete the syllabus and solve previous years' papers and mock tests.
