Trends in NEET Weightage: 2025 vs Previous Years

To prepare effectively for NEET 2025, it’s important to understand how the weightage of topics has evolved in recent years. By analysing the past few years of NEET exams, we can identify patterns and anticipate potential shifts in topic importance.


Physics:

  • Previous Trends: In recent years, topics like Mechanics (especially Laws of Motion and Work, Power & Energy) and Modern Physics (Atomic Structure, Nuclei) have consistently carried significant weight.

  • 2025 Prediction: Based on previous years, we expect Mechanics, Modern Physics, and Thermodynamics to remain high-weightage areas. However, Electrostatics and Magnetic Effects of Current might see a slight increase in the number of questions, reflecting the growing importance of foundational concepts in these areas.


Chemistry:

  • Previous Trends: Physical Chemistry (especially Thermodynamics, Equilibrium, and Solutions) has traditionally accounted for a large portion of the questions. Similarly, Inorganic Chemistry topics like Coordination Compounds and p-Block Elements have held steady weight.

  • 2025 Prediction: For NEET 2025, Inorganic Chemistry and Physical Chemistry are likely to retain their dominance, with a noticeable increase in questions related to Organic Chemistry—specifically, Name Reactions and Biomolecules. Environmental Chemistry is also expected to gain importance due to growing environmental concerns.


Biology:

  • Previous Trends: Human Physiology and Ecology have been high-weightage areas in recent years, contributing significantly to the total score. Botany (specifically Plant Physiology and Genetics) has also been a consistent focus.

  • 2025 Prediction: We anticipate Human Physiology, Ecology, and Genetics to remain top-priority chapters. However, there may be an increase in questions on Biotechnology and Environmental Studies, reflecting the growing relevance of these fields in both the academic curriculum and the medical profession.


Predicted Questions for NEET 2025 Based on Past Trends

By studying the trends from previous NEET exams, we can predict which types of questions are most likely to appear in NEET 2025.


  • Physics:

    • Mechanics: Expect 8-10 questions on topics like Laws of Motion, Work, Energy, Power, and Circular Motion. These topics have consistently been a large source of questions.

    • Modern Physics: 5-7 questions could come from Atoms and Nuclei, Semiconductor Electronics, and the Dual Nature of Matter.

    • Optics & Thermodynamics: 6-8 questions are expected, with a balanced focus on both Ray Optics and Wave Optics, as well as the Laws of Thermodynamics.

  • Chemistry:

    • Inorganic Chemistry: Around 8-10 questions could be dedicated to Chemical Bonding, Coordination Compounds, and p-Block Elements, as these are historically strong topics.

    • Organic Chemistry: 6-8 questions are likely to come from Biomolecules, Carbonyl Compounds, and Hydrocarbons, which have been gaining prominence in recent exams.

    • Physical Chemistry: 6-8 questions are expected from Thermodynamics, Chemical Kinetics, and Mole Concept, which have consistently held a significant portion of the total marks.

  • Biology:

    • Human Physiology & Genetics: Expect 12-15 questions from topics like Human Physiology, Human Reproduction, Genetics, and Ecology, which have consistently appeared as the most weighted sections in NEET Biology.

    • Botany: Plant Physiology, Ecology, and Cell Biology could each contribute around 8-10 questions, reflecting their importance.

    • Zoology: Animal Physiology and Human Health are predicted to bring in 8-10 questions, maintaining their steady presence in the exam.
