JEE Physics Exam 2025 Weightage Analysis

Here’s a breakdown of the estimated weightage for different chapters:

High Weightage (20-30%)

  • Modern Physics: This chapter consistently holds significant weightage due to its vast applications and connection to various scientific advancements. Be prepared for questions on atomic structure, the dual nature of matter, photoelectric effect, nuclear physics, radioactivity, and Einstein’s theory of relativity.
  • Electromagnetic Waves: Understanding the properties and behavior of electromagnetic waves across the spectrum (radio waves to gamma rays) is crucial. Expect questions on the photoelectric effect, Compton Effect, and their implications.
  • Ray Optics and Optical Instruments: Mastering the principles of reflection, refraction, lenses, mirrors, and their applications in instruments like microscopes and telescopes is essential for this high-weightage section.

Medium Weightage (15-20%)

  • Current Electricity: This chapter forms the backbone of circuit analysis. Expect questions on electric current, Kirchhoff’s Laws, resistance, potential difference, and solving problems involving series and parallel circuits.
  • Magnetic Effects of Current and Magnetism: Understanding the magnetic field generated by currents, electromagnetic induction, AC circuits, and the magnetic properties of materials is important for this section.
  • Laws of Motion and Work, Power & Energy: Mastering Newton’s Laws of Motion, their applications to various scenarios, and concepts like work, power, and energy is vital for this medium-weightage section.
  • Oscillations and Waves (excluding Doppler Effect): This chapter covers simple harmonic motion, wave superposition, and sound waves. While the Doppler Effect might have a lower weightage, understanding the core concepts is still recommended.

Low Weightage (10-15%)

  • Kinematics: Focus on understanding concepts like distance, displacement, speed, velocity, acceleration, projectile motion, and uniform circular motion.
  • Gravitation: Grasp the concept of universal gravitation, Kepler’s Laws, and solve problems involving gravitational potential and escape velocity. There might be fewer questions from this section compared to others.
  • Properties of Solids and Fluids: Explore concepts like elasticity, surface tension, viscosity, fluid pressure, and Archimedes’ Principle. The weightage for this section might be on the lower side.
  • Measurement and Units: Mastering dimensional analysis, unit conversions, and significant figures is crucial for tackling problems across all chapters. However, dedicated weightage for this topic might be minimal.

Remember, consistent practice and a deep understanding of concepts are key to conquering JEE Physics. Utilize this weightage analysis as a guide to strategize your preparation and prioritize your learning effectively.
