  • January 29, 2026

The final examination day of JEE Main 2026 Session 1 was conducted on 28th January 2026, marking the conclusion of the first phase of this highly competitive engineering entrance exam. Thousands of aspirants appeared in both the Morning Shift (Shift 1) and Evening Shift (Shift 2) across multiple test centers.

Based on student responses, memory-based question recall, and expert faculty analysis, this detailed review highlights the difficulty level, subject-wise trends, scoring opportunities, and preparation insights from the last day of Session 1.

JEE Main 2026 – January 28 Exam Day Overview

The overall performance trend on 28th January reflected a moderate difficulty level across both shifts. However, the type of challenges faced by students varied between the morning and evening sessions. Understanding this shift-wise variation helps aspirants analyze exam trends more effectively.

Both shifts on 28th January were placed in the moderate difficulty category, but the nature of challenges differed between the two sessions.

Key Observations of the Day

  • Mathematics was the most challenging subject in both shifts
  • Physics was more scoring in the morning shift
  • Chemistry proved to be the most balanced and reliable section in the evening shift
  • Time management played a critical role in overall performance

This variation once again confirmed that consistent preparation across all subjects is essential.

Shift 1 (Morning) Analysis – Mathematics Tested Speed and Accuracy

The morning shift paper focused strongly on calculation efficiency and smart question selection. While the overall difficulty remained moderate, students reported that managing time—especially in Mathematics—was the biggest challenge. This shift required balanced preparation and quick decision-making.

  • Overall Difficulty Level: Moderate
  • Expected High Percentile Score Range: 170 – 180 marks (initial estimate)

Physics Analysis – Formula-Based and Student-Friendly

Physics in the morning shift was considered one of the more comfortable sections for many students. With a strong focus on formula application and fundamental concepts, this section rewarded candidates who had revised standard equations and practiced numerical problem-solving regularly.

  • Nature of Questions: Numerical and conceptual with straightforward calculations
  • Syllabus Distribution: Majority of questions were from Class 12 topics
Important Topics Covered
  • Mechanics
  • Electrostatics
  • Heat and Thermodynamics
  • Current Electricity

Students who had strong command over basic formulas were able to complete this section quickly and confidently.

Chemistry Analysis – Moderate with Analytical Touch

Chemistry in Shift 1 required careful reading and conceptual understanding. Although many questions were based on NCERT, the inclusion of statement-based and application-oriented problems made this section slightly more analytical compared to earlier days of Session 1.

  • Difficulty Level: Moderate
  • Pattern: Statement-based and concept-oriented
Topic Distribution:

Physical Chemistry:

  • Atomic Structure
  • Ionic Equilibrium

Organic Chemistry:

  • Hydrocarbons
  • Aromatic Compounds

Inorganic Chemistry:

  • Coordination Compounds

A good understanding of NCERT theory and reaction concepts was essential for scoring well.

Mathematics Analysis – The Main Challenge

Mathematics emerged as the most demanding subject in the morning shift due to lengthy calculations and multi-step problems. Even though most questions were from familiar topics, the time required to solve them made this section the deciding factor for many students.

  • Difficulty Level: Moderate
  • Nature: Lengthy calculations with multiple steps
Approximate Topic Weightage:
  • Algebra – Highest contribution
  • Calculus – Significant portion
  • Coordinate Geometry
  • Vectors and 3D Geometry
  • Trigonometry

Although most questions were not conceptually very difficult, students struggled to attempt all questions due to time pressure.

Shift 2 (Evening) Analysis – Conceptual Depth in Mathematics

The evening shift continued the moderate difficulty trend but introduced deeper conceptual challenges, especially in Mathematics. Students found that logical reasoning and step-by-step problem-solving played a greater role in this shift compared to simple formula application.

  • Overall Difficulty Level: Moderate
  • Expected High Percentile Score Range: 175 – 185 marks (initial estimate)

Physics Analysis – Balanced and Concept-Focused

Physics in the evening shift maintained a balanced structure with a mix of theoretical and numerical questions. This section tested conceptual clarity rather than speed alone, making it important for students to have a strong understanding of core principles.

  • Difficulty Level: Easy to Moderate
  • Pattern: Combination of numerical and conceptual questions
Major Topics Asked
  • Electrostatics
  • Modern Physics
  • Optics
  • Thermodynamics

Some assertion-reasoning and statement-type questions were reported, making conceptual clarity important.

Chemistry Analysis – Most Reliable Scoring Section

Chemistry remained one of the most stable and scoring sections in the evening shift. With a strong NCERT foundation and balanced topic distribution, students who prepared systematically found this section easier to manage under exam pressure.

  • Difficulty Level: Moderate
  • Nature: NCERT-based with balanced coverage
Frequently Asked Topics
  • Coordination Compounds
  • Chemical Kinetics
  • Ionic Equilibrium (Buffer solutions)
  • Amines and basic Organic Chemistry

Students who revised NCERT thoroughly found this section easier to attempt with good accuracy.

Mathematics Analysis – Conceptually Tricky and Calculation-Heavy

Mathematics in Shift 2 was widely regarded as the toughest section of the day. Instead of being only lengthy, the problems required deeper thinking and multi-step calculations, making it a crucial differentiator for higher percentiles.

Nature: Multi-step reasoning and complex calculations

High Weightage Topics
  • Calculus (Integration)
  • Algebra (Sequence and Series, Probability)
  • Coordinate Geometry

This section acted as the main differentiator for higher percentiles.

Expert Preparation Insights from ALLEN Overseas for Session 2:

Based on detailed student feedback and faculty analysis, several strategic preparation patterns became clear. These insights highlight what worked well for students and what needs stronger focus for upcoming exam attempts.

Based on the analysis of both shifts, ALLEN Overseas experts suggest the following strategies:

Focus on NCERT for Chemistry

  • Revise theory lines carefully
  • Pay attention to exceptions and tables
  • Practice Inorganic and Physical Chemistry from NCERT

Improve Calculation Speed in Mathematics

  • Practice mixed-topic problems daily
  • Focus on accuracy and speed
  • Strengthen Calculus and Algebra problem-solving

Strengthen Physics Fundamentals

  • Revise formulas regularly
  • Practice numericals from Mechanics and Electromagnetism
  • Focus on conceptual understanding

Build a Flexible Exam Strategy

  • Start with stronger subjects to gain confidence
  • Avoid spending too much time on one question
  • Practice full-length mock tests regularly

The 28th January JEE Main 2026 Session 1 paper reinforced that success in JEE Main depends on balanced preparation, strong fundamentals, NCERT-based learning, and efficient time management.

While Physics and Chemistry provided scoring opportunities, Mathematics continued to play a decisive role in ranking performance. Aspirants preparing for Session 2 or future attempts should use this analysis to refine their revision strategy and focus on high-weightage topics.
