Physics Concept Weightage

Physics Concept Weightage 

General concept weightage analysis for the NEET exam based on trends observed in recent years. This analysis gives an idea of the distribution of questions across different topics in Physics, Chemistry, and Biology, helping students focus their preparation on high-weightage areas.

1. Physics Concept Weightage (2020-2023)

Physics is considered one of the more challenging sections in NEET, and the distribution of questions is relatively consistent, covering Class 11 and Class 12 topics.

Key Topics and Weightage:

• Mechanics (Laws of Motion, Work-Energy-Power, Rotational Motion) – 25-30%
• Electrodynamics (Current Electricity, Electrostatics, Magnetism) – 20-25%
• Optics (Ray and Wave Optics) – 8-10%
• Thermodynamics – 6-8%
• Modern Physics (Dual Nature of Matter, Atomic Structure) – 10-12%
• Waves and Oscillations – 6-8%
• Properties of Matter (Fluids) – 4-6%

Recent Trend:

• Mechanics and Electrodynamics consistently contribute a significant portion of the Physics section.
• Thermodynamics and Optics are also frequently featured, with a few questions each year.

Here is a chapter-wise weightage analysis for Physics based on recent NEET exams (2020-2023). This breakdown will help you understand which chapters carry more importance, allowing you to prioritize your preparation accordingly.
