In this article, we will explore the NEET UG 2025 high-scoring chapters across Physics, Chemistry, and Biology, giving you the best possible chance of scoring high in the exam. We will break down the most important chapters, based on their weightage, frequency of appearance in previous exams, and overall difficulty level.
Understanding NEET UG 2025 Exam Pattern and Weightage
Before diving into the high-scoring chapters, it is essential to understand the NEET UG exam pattern. The exam consists of three subjects: Physics, Chemistry, and Biology (Botany and Zoology). The total number of questions is 200, out of which candidates must attempt 180 questions.
- Physics: 50 questions
- Chemistry: 50 questions
- Biology: 100 questions (Botany and Zoology)
The exam is based on the NCERT curriculum, and the questions are divided equally across the three subjects. Each question carries four marks, and incorrect answers are penalized with one mark deducted.

- Genetics and Evolution: This chapter is often scored and appears frequently in NEET UG. Focus on Mendelian genetics, genetic disorders, and the principles of evolution.
- Ecology and Environment: While this chapter may not be as lengthy as others, it holds high importance and is relatively straightforward. Pay attention to ecosystems, environmental issues, and biodiversity.
How to Approach High-Scoring Chapters in NEET UG 2025
- Prioritize High-Weightage Chapters
Given the time constraints during preparation, prioritize chapters with higher weightage and frequency of appearance. Mechanics, Modern Physics, Thermodynamics, Organic Chemistry, and Human Physiology are examples of chapters that should be your primary focus.
- Plan Your Study Schedule
Create a study schedule that allocates more time to high-scoring chapters, ensuring that you give yourself enough time to revise and practice problems related to these topics.
- Use NCERT Books
Since most questions in NEET UG are derived from NCERT textbooks, make sure you thoroughly understand the chapters in these books, especially for subjects like Biology and Inorganic Chemistry.
- Practice Regularly with Mock Tests
After mastering the high-scoring chapters, take regular mock tests to improve your speed and accuracy. Mock tests also help you identify weak areas and areas that require further revision.
- Revise Frequently
Frequent revision is key to retaining information. Revise high-scoring chapters regularly, especially before the exam, to keep the concepts fresh in your mind.
Conclusion
