JEE Main 23 January 2026 – Shift 1 (Morning) – Paper Analysis
The morning shift of 23 January 2026 was assessed as moderate and well-balanced, with questions designed to test conceptual understanding and application rather than rote memorisation. Compared to earlier exam days, this shift was less time-consuming, especially in Mathematics.
Physics
- Overall difficulty: Moderate
- Topic distribution: Mechanics, Current Electricity, Electrostatics, Modern Physics, Optics
Detailed analysis:
- The paper featured a healthy mix of conceptual and numerical problems.
- Mechanics questions tested fundamentals such as Laws of Motion and Work-Energy, mostly single-concept based.
- Current Electricity and Electrostatics required formula application with basic calculations.
- Modern Physics was direct and scoring, with theory-based and formula-driven questions.
- Overall, Physics was approachable for students with clear fundamentals.
Chemistry
- Overall difficulty: Easy to Moderate
- Topic distribution: Inorganic Chemistry (dominant), Organic Chemistry, Physical Chemistry
Detailed analysis:
- Inorganic Chemistry was largely NCERT-based, with straightforward questions on periodic trends, coordination compounds, and chemical bonding.
- Organic Chemistry focused on fundamental reaction mechanisms and basic conversions rather than complex synthesis.
- Physical Chemistry included standard numericals from Thermodynamics and Chemical Kinetics.
- Chemistry emerged as the most scoring section of the paper.
Mathematics
- Overall difficulty: Moderate
- Topic distribution: Algebra, Calculus, Coordinate Geometry, Trigonometry
Detailed analysis:
- Algebra questions were direct and scoring, particularly from Matrices and Determinants.
- Calculus questions were of moderate length, testing understanding of differentiation and basic integration.
- Coordinate Geometry questions required careful calculation but were not conceptually difficult.
- Mathematics was less lengthy than several previous shifts, allowing better time management.
Overall Assessment
- Balanced paper with no extreme difficulty spikes
- Chemistry and Physics offered scoring opportunities
- Mathematics tested accuracy rather than speed
- Well-prepared students could attempt a high number of questions confidently

| 150–170 marks | 95.0–97.0 percentile |
| 120–140 marks | 92.0–94.5 percentile |
| 90–110 marks | 88.0–91.5 percentile |
Normalization in JEE Main 23 January 2026 (Shift 1)
- Percentiles are calculated within the shift based on relative performance.
- These percentiles are aligned with all other shifts across January and April.
- Final All India Rank (AIR) is prepared using normalized percentile scores, not raw marks.
- Minor differences in shift difficulty are neutralized through normalization.
In essence: Candidates from 23 January Shift 1 are evaluated equitably against all other shifts and sessions, with difficulty differences neutralized.
