Subject-Wise JEE Main 2026 Shift 1 Analysis
Physics Question Paper Analysis – Shift 1
Physics in the 1st shift were graded moderate from the vast majority of students. The essay focused on fundamental concepts of Class 11 and 12. It also included the right mix of theoretical and numerical questions. Questions based on formulas were the most popular students with clear conceptual understanding were able to handle this section.
The most important observations:
- There aren’t any extremely difficult or confusing questions.
- Numerical Value Questions were based on calculations but were easy to answer.
- The balance of weightage in Mechanics Electricity, Mechanics, and Modern Physics
Physics Topic-Wise Distribution
| Topic | Number of Questions |
| Optics (Microscope, Power of Lens) | 2 |
| Semiconductor (Logic Gates) | 1 |
| Units & Dimensions (Errors, Dimensions) | 2 |
| Current Electricity | 1 |
| Calorimetry | 1 |
| Rotational Motion (Moment of Inertia) | 1 |
Difficulty Level: Moderate
Good Attempt (Physics): 18–20 questions
Chemistry Question Paper Analysis – Shift 1
Chemistry was the highest scoring subject in JEE Main 2026 – 21 January Shift 1. The majority of the questions stemmed directly taken from NCERT particularly on Inorganic Chemistry and Organic Chemistry. Students who reviewed NCERT thoroughly discovered this section to be easy to understand.
Important Observations:
- NCERT-based questions on factual issues dominating
- Organic Chemistry had direct reaction-based questions
- Physical Chemistry questions were formula-based
Special Note:
“Glass-based questions” from Organic Chemistry were reported, which suggests a direct application of concepts rather than complex mechanisms.
Chemistry Topic-Wise Distribution
| Topic | Number of Questions |
| Thermal Properties of Fluids (Bernoulli’s Theorem) | 1 |
| Optics | 2 |
| Semiconductor (Logic Gates) | 1 |
| Units & Dimensions | 2 |
| Current Electricity | 1 |
| Calorimetry | 1 |
| Rotational Motion (MOI) | 1 |
(Note: Chemistry topics were largely NCERT-aligned despite interdisciplinary overlaps reported by students.)
Difficulty Level: Easy to Moderate
Good Attempt (Chemistry): 20–23 questions
Mathematics Question Paper Analysis – Shift 1
Mathematical reasoning was thought to be the most demanding section of the exam. Although the difficulty was moderate, many of the questions were extremely long and required multiple-step calculations. Students who had a high rate of problem-solving were more successful.
Key Observations:
- Calculus had fewer questions than expected
- Emphasis on Algebra and Coordinate Geometry
- Some questions were lengthy but conceptually simple
Important Maths Topics Reported:
- Trigonometry
- Coordinate Geometry
- Domain-based questions
- Sets & Relations
Mathematics Topic-Wise Distribution
| Topic | Number of Questions |
| Calculus | Fewer questions |
| Vector Algebra & 3D Geometry | 2–3 |
| Quadratic Equations | 1 |
| Matrices | 1 (Lengthy) |
| Sets & Relations | 2 |
Difficulty Level: Moderate
Good Attempt (Mathematics): 12–15 questions
Expected Good Attempts – Shift 1 (Overall)
Based on overall student feedback and paper difficulty:
| Subject | Good Attempt Range |
| Physics | 18–20 |
| Chemistry | 20–23 |
| Mathematics | 12–15 |
| Overall | 50–55 questions |
Students attempting to score within this range with high accuracy should be able to achieve an impressive percentile upon normalization.
Comparison With Upcoming JEE Main 2026 Shifts
As the first shift of Session 1 21 January shift 1 paper is an example for comparison of difficulty and normalization. The past has shown that NTA keeps a steady equilibrium across shifts, but small variations can occur.
