JEE Main 2025 April 7 Shift 1 Paper Analysis: The National Testing Agency successfully concluded the fourth day of the Joint Entrance Examination (JEE) Main 2025 on April 7. The JEE Main exams is being conducted in two shifts on each exam-day. The first shift is scheduled from 9 am to 12 noon, while the second shift will take place between 3 pm and 6 pm.
Paper 1, which is for BE or BTech courses, includes a total of 75 multiple-choice questions (MCQs) carrying 300 marks. Unlike previous years, Section B of Paper 1 will not include optional questions. Instead, candidates will be required to attempt all five questions per subject in this section.
The the overall difficulty level of the JEE Main 2025 paper ranked Mathematics as the most challenging, followed by Physics and then Chemistry.
Mathematics
According to Ajay Sharma, National Academic Director, Engineering at Aakash, Mathematics was the most challenging section in the JEE Main 2025 paper. While the questions were spread across the syllabus, topics like 3D Geometry, Vectors, and Conic Sections carried the highest weightage. Matrices and Calculus had comparatively fewer questions.
Several problems were lengthy, requiring extensive calculations and multiple steps, which made time management particularly difficult. This section demanded both conceptual clarity and strong problem-solving speed, making it the toughest of the three subjects.
“Mathematics was notably lengthy and calculation-intensive, with significant emphasis on Calculus, 3D Geometry, and Probability,” said Ujjwal Singh, founding CEO, Infinity Learn by Sri Chaitanya.
Chemistry
Sharma noted that Chemistry was the most straightforward among the three sections, offering high scoring potential. The section featured a significant number of statement-based questions, most of which were simple and factual.
Singh also said that Chemistry, mirrored those from previous sessions, underscoring the importance of thorough NCERT study and practice with past papers. He said that the Chemistry was the most scoring section, comprising numerous direct NCERT-based questions, particularly from Biomolecules and Coordination Compounds.
The weightage was highest for Organic Chemistry, followed by Inorganic Chemistry, while Physical Chemistry had the least representation. Key chapters included Chemical Kinetics and Solutions.
Notably, the majority of the questions were theory-based and directly sourced from the NCERT textbook, especially in the Physical Chemistry portion.
Physics
The Physics section in the JEE Main 2025 ranged from easy to moderate difficulty. The paper was largely dominated by numerical and formula-based questions, giving an edge to students with strong conceptual understanding.
Prominent topics included Mechanics, Modern Physics, Electrostatics, Ray Optics, and Units & Measurements. Interestingly, there were no questions from Fluids, Wave Optics, or Electromagnetic Induction (EMI). While a few problems required careful calculation, most were direct and scoring, offering a balanced mix for students.
On the other hand, Singh claimed that Physics was conceptually driven, featuring questions from Modern Physics, Current Electricity, and Rotational Motion.
In the evening shift, Ajay Sharma claimed that the exam was moderate. He said that JEE Main session two was thoughtfully and balanced across all three subjects. Chemistry turned out to be easy, Physics had a mix of simple and moderately tough problems, while Mathematics stood out as the toughest, largely due to its lengthy and calculation-heavy questions.
Physics
For Sharma the Physics section had majority of questions from numerical and formula-driven, which required precision and quick recall. Mechanics, Units & Measurements, Electrostatics, and Optics were the dominant topics with no questions from Electromagnetic Induction (EMI), and only a few from Oscillations, Waves, Magnetism, and Thermodynamics. Some calculations were a bit time-consuming, but nothing overly complex.
Chemistry
Ajay claimed Chemistry to be the easiest among all the sections with significant number of questions straightforward, statement-based questions. The paper covered nearly all topics, with Organic Chemistry leading in terms of weightage, trailed by Inorganic. Physical Chemistry appeared minimally, with a few questions on Chemical Kinetics and Solutions. Most theory questions were lifted directly from the NCERT, and even Physical Chemistry leaned more toward theory than math-based problems.
Mathematics
Mathematics according to Ajay Sharma demanded the most efforts with questions fairly distributed across chapters, topics like 3D Geometry, Vectors, and Conic Sections received the most attention. In contrast, Matrices and Calculus saw lighter coverage. Many problems were calculation-intensive, making time management a critical factor. For many students, this section was the most exhausting.
