JEE Main is a computer-based online test administered by the National Testing Agency (NTA) for candidates interested in enrolling in undergraduate engineering programmes at prestigious engineering colleges in India. There were 2 Sessions of the JEE Main 2023, which was the qualifying exam for the JEE Advanced 2023. This engineering entrance is pretty challenging and requires a proper preparation approach.
When it comes to a strategic approach, analysing the previous years’ exams can do wonders for the JEE aspirants. This page will highlight the detailed breakdown of JEE Main 2023 paper analysis for all four sessions.
This analysis is based on feedback from India’s JEE experts and the students who took the exam. The paper analysis will help students understand the level of difficulty of questions and every topic with its weightage. Candidates can use this question paper analysis to prepare for the upcoming JEE exams.
JEE (Main) 2023 Session 1 Exam will be held from 24th January to 31st January, 2023. According to the students, the paper was moderately difficult. Topic coverage was fairly balanced in all three subjects. There were several good questions in the paper. Overall, Mathematics was the most difficult, whereas Physics and Chemistry were on the easier side.
Mathematics - Mathematics was moderate for the majority of students. Some questions, as expected, required extensive calculations. There were eight problems from calculus, seven from algebra, three to four from vectors in three dimensions, and four from coordinate geometry. Trigonometry also had a place in this part. Regular practice and mock examinations would be quite beneficial in scoring well on these sorts of questions.
Physics - Physics paper was easy for most of the students. Questions were asked from all major chapters, including two from optics, five from mechanics, two or three from thermodynamics, and one each from communication systems, experimental physics, and units and measurements, among others. Six questions on electricity and magnetics were asked. There were also questions regarding waves and oscillations, as well as current. As predicted, numerical questions had more numbers than theoretical questions, and practically all numerical questions were formula-based questions.
Chemistry - This paper was simple to moderate, and the entire paper was based on NCERT. There were about equal numbers of problems from the Physical, Inorganic, and Organic areas of Chemistry. The majority of the numerical value-based problems were from Physical Chemistry. Along with usual topics, the publication included chapters on biomolecules, polymers, chemistry in everyday life, and environmental chemistry.
According to the initial reactions of students who had taken the test, the question paper's degree of difficulty was moderate, but the mathematics section was challenging. The easiest of the three topics was physics. Let's go into further details:
Mathematics - Moderately difficult level. Algebra & Calculus were given more weight in the questions than nearly all other chapters. Questions from the circles and ellipses have mixed ideas of being difficult or moderate. Permutation and combination, two questions of probability, three questions from matrices, quadratic equations, and complex numbers in algebra were also covered in the problems. There were 2 to 3 questions on differential equations in calculus. 3D Geometry & Vectors had three questions. According to the students, the calculations for the numerically based questions were lengthy.
Physics - Overall, this was a well-balanced portion. Gravitation, Laws of Motion, Fluids, SHM, Work, Rotational Motion, Power & Energy, Heat & Thermodynamics, Kinematics, Electrostatics, Current Electricity, Magnetism, AC Circuits, and Communication Systems were among the scoring topics. Optics and Current Electricity both had more than two questions. The numerical problems were simple.
