Biology is still the most-scoring and highest-weightage subject in the NEET UG entrance test. With close to 50% weightage for Biology in the total NEET UG paper, mastering PYQs is no longer a choice but a challenge that one has to face. With the growing competition for NEET UG 2026, practicing the Biology PYQs can help one score high, giving accuracy, speed, and conceptual clarity a boost.
In this post, we tell you why Biology PYQ is important and list out the Top 20 most important Biology PYQ topics that every NEET UG aspirant should solve before appearing for the exam.
Importance of Biology PYQs For NEET UG 2026
NEET UG is based on NCERT concepts, and many of the questions in the biology section are picked directly or indirectly from previous year question papers. Based on the trend of exams over the past decade, we know that:
Many questions are conceptually repeated
NCERT lines are directly tested
Increment in the questions based on Assertion and Reason, statement-type questions
PYQs are something that helps candidates know exam temperament, eliminates guesswork, and weighs up the high-yield chapters.
NEET UG Biology: Weightage Overview
Biology, which is part of Botany and Zoology, has 90 questions (360 marks). As per the norms laid down by the National Medical Commission (NMC), there is no amendment in the syllabus, and it is entirely based on NCERT Class 11 and 12 Biology for NEET.
So, intelligent aspirants can rely upon PYQs to rank chapters based on the frequently asked questions.
20 Most Important Biology PYQ Topics for NEET UG 2026
Class 11 Biology – High-Yield Previous Year Questions
Cell: Structure and Function – Functions of organelles, cell theory
Biomolecules – Enzymes, carbohydrates, and protein structures
Stages of Cell Cycle and Stages of Mitosis vs. Meiosis
Light reaction and Calvin cycle of higher plants -Photosynthesis
Respiration in Plants – Glycolysis, Krebs cycle, and ETS
Growth and Development in Plants – Hormones and Their Functions
Anatomy of Animals – Identification of tissue structure
Neural Control and Coordination – Reflex action, synapse
Chemical coordination and integration – #Endocrine glands
42 Digestion and Absorption of Carbohydrates– Enzymes and Disorders
These chapters bring together around 45–50% of Class 11 Biology PYQs.
Class 12 Biology – Most Repeated PYQs Read Now
Principles of Inheritance and Variation – Mono, dihybrid inheritance, crosses of Mendel, Pedigree analysis
Inheritance- Reproduction of Organisms Chapter 9.
Evolution – Hardy-Weinberg principle, homologous vs analogous
Human Reproduction – Gametogenesis, menstrual cycle 1.
Reproductive Health – Contraceptives, STDs

These chapters cover a significant portion of Class 12 Biology, which has been known to be weighted more heavily than the content in Class 11.
Accuracy And Rank Boon Of PYQs
Multiple analysis indicates that candidates who solve Biology PYQs multiple times:
Get a higher score with fewer negative marks
Recognize repeated NCERT lines instantly
Raise awareness about time management in the exam hall
The NEET rank predictor after mock tests will help candidates to understand the value of mastering Biology PYQs in finishing right on top in their All India Rank (AIR).
There is an increasing demand for biology skills in the world at large.
A good base of Biology is necessary not only for NEET UG but for a long-term study of medical education, including clinical practice. Medical schools listed on the World Directory of Medical Schools are compliant with international requirements for health care, and they focus on strong conceptual knowledge starting at the UG curriculum.
Additionally, World Health Organization (WHO) endorsed healthcare curricula recognize that medical graduates need to be grounded in traditional life sciences.
Best Way to Practice Biology PYQs for NEET UG 2026
To maximize results:
Solve past 10-15 yrs PYQs chapterwise
Match the following with respect to the NCERT lines.
Revise incorrect questions weekly
Focus more on statement-based PYQs
Avoid learning outside the NCERT unnecessarily
Consistency matters more than volume.
Conclusion
Biology PYQs are a lifeline for the NEET UG 2026 exam. The Top 20 areas noted above represent the number of questions you should expect based on these subject topics. This is also reflected in our competitors’ products. As the exam is getting more and more NCERT-based, PYQ-oriented preparation is the best way to success.
Turning NEET UG preparation in sync with the trend, matching to NMC approved syllabus and keeping abreast of global standards as framed by WDOMS (World Directory of Medical Schools) and the WHO framework of town together a student towards top medical colleges in India.
