JEE Main 2025 January Session Analysis

3/13/2025

The January 2025 session of JEE Main has concluded with notable changes in both pattern and weightage distribution. The National Testing Agency (NTA) has restructured the subject weightage, increasing Mathematics to 35% while reducing Physics and Chemistry to 22.5% each. This shift represents a significant departure from previous years' equal distribution, putting greater emphasis on mathematical aptitude.

Subject-wise Analysis

Mathematics: The Mathematics section emerged as the most challenging component across all shifts, characterized by moderate to difficult questions requiring lengthy calculations. Topics from Class 12 dominated, particularly Calculus, 3D Geometry, Vectors, and Conic Sections. The increased weightage of Mathematics necessitates greater focus on high-yield topics like Coordinate Geometry and Algebra, which consistently feature prominently. Time management became crucial as many questions involved extensive calculations despite not being conceptually complex.

Physics: The Physics section was generally perceived as easy to moderate across most shifts. Class 12 topics received greater representation than Class 11 concepts. Modern Physics emerged as the highest weightage chapter (approximately 15.9% of the total marks), followed by Current Electricity, Electrostatics, Thermodynamics, and Optics (each contributing around 9.9%). Notably, January 24th's shift saw fewer questions from Mechanics, Waves, and Thermodynamics, while Optics and Electromagnetism gained prominence. The pattern consistently featured formula-based and conceptual questions over calculation-intensive problems.

Chemistry: Chemistry proved to be the most approachable section, providing a strategic time advantage to well-prepared candidates. The distribution varied across shifts, with the January 23rd paper emphasizing Organic Chemistry, while other shifts gave more weightage to Inorganic Chemistry. High-weightage chapters included Classification of Elements and Periodic Table, Transition Elements and Coordinate Geometry (9.9% each), followed by Atomic Structure, Chemical Bonding, and Equilibrium (6.6% each). Most questions aligned closely with NCERT content, continuing the trend from previous years.

Pattern Analysis and Difficulty Comparison

The overall paper maintained moderate difficulty comparable to previous years, with no significant structural changes reported. Subject experts noted that the paper followed last year's pattern with mathematics continuing its tradition of being lengthy and challenging. The January 27th shift analysis by FIITJEE indicated physics was particularly easy, with significant representation from Modern Physics. The consistent emphasis on NCERT-aligned content continues from previous years, especially in Chemistry.
