The first shift of the JEE Main 2026, held on January 21st, has concluded, and initial student reactions and expert reviews are pouring in, painting a picture of a moderately challenging exam. The difficulty level varied across subjects, with Chemistry surprising many, while Mathematics was considered lengthy. Here’s a detailed breakdown of the subject-wise difficulty levels:

Mathematics:

Mathematics was generally perceived as moderate, but time-consuming. Students reported the questions to be tricky and requiring strong calculation accuracy and good time management. Key topics covered included Calculus, 3D Geometry, Vectors, Algebra, and Probability. Some students found the Maths section easier to understand than the previous year's exam, although it still took the most time. Experts noted that the Mathematics section was the most challenging due to its length and complex calculations. Focus should be given to Vectors & 3D Geometry, Matrices & Determinants, Limits & Continuity, and Differential Calculus.

Physics:

The Physics section was considered moderate overall, with a mix of conceptual and formula-based questions. Questions primarily came from Mechanics, Modern Physics, Current Electricity, Optics, and Thermodynamics. Some students found the Physics section to be relatively easier compared to Maths but more challenging than Chemistry. A strong understanding of concepts was crucial for tackling the Physics questions. High weightage topics include Modern Physics, Current Electricity, Units & Dimensions, Kinematics, and Laws of Motion.

Chemistry:

Contrary to expectations, Chemistry was considered moderately difficult and lengthy by many students. Several assertion-type questions and statement-based questions contributed to the challenging nature of this section. Questions covered all three branches of Chemistry: Physical, Organic, and Inorganic. Coordination Compounds, Chemical Bonding, Organic Reaction Mechanism, and Environmental Chemistry were among the key topics. Some students felt that preparation through online resources did not fully align with the questions asked. Focus should be given to Inorganic Chemistry, GOC, Coordination Compounds and Chemical Bonding.

• Physical Chemistry: Questions were calculation-oriented and time-consuming, requiring precision.
• Inorganic Chemistry: Questions were largely NCERT-based and conceptually simple but sometimes lengthy.
• Organic Chemistry: The section focused on understanding reaction mechanisms rather than rote memorization.

Overall:

The overall difficulty of the JEE Main 2026 January 21 Shift 1 paper was moderate to tough. The Chemistry section played a decisive role in score differentiation. A score of approximately 110 marks is projected to be the qualifying threshold for JEE Advanced eligibility based on preliminary trends. Test takers cited time management as critical for success.
