NEET UG Chemistry Syllabus 2025: Chapter-wise Weightage, Syllabus, Strategy etc.

The NEET UG exam includes three subjects – Physics, Chemistry and Biology. This article focuses on the chapter-wise weightage of Chemistry. To prepare effectively for NEET UG chemistry syllabus 2025 candidates must understand the subject-wise weightage. Chemistry is divided into three key areas – Physical Chemistry, Organic Chemistry and Inorganic Chemistry. By analyzing the distribution of marks across these areas, students can prioritize their studies and strengthen weaker sections to improve their scores.

A clear understanding of the weightage not only increases the potential for scoring higher but also boosts confidence in tackling difficult problems in the exam. With a clear understanding of the weightage, aspirants can plan their revisions more efficiently, at last enhancing their overall performance in the Chemistry section.
