National Testing Agency, NTA has concluded JEE Mains Exam 2023 Shift 2 on January 31, 2023. The difficulty level of exam was easy to moderate. The Chemistry and Physics section was easy and Mathematics section was tough.
The reporting time for students was 1:20 pm however the exam started sharp at 3:00 pm. Immediate reaction from students after the exam
There were total 90* questions and Total marks of JEE Main Paper-1 was 300. (* 5 out of 10 questions were to be attempted from Numerical Based section in each subject). The paper had three parts & each part had two sections:
JEE Main Exam 2023: Paper Pattern
Part-I– Physics had total 30*questions – Sec-I had 20 Multiple choice questions with Single correct answers & Sec-II had 10 Numerical based questions out which only 5 had to be attempted. Marking scheme for multiple choice questions was +4 for correct response, -1 for incorrect response, 0 if not attempted. Marking scheme for numerical based questions was +4 for correct response, -1 for incorrect response and 0 in all other cases. Total marks of this section were 100.
Part-II– Chemistry had total 30*questions – Sec-I had 20 Multiple choice questions with Single correct answers & Sec-II had 10 Numerical based questions out which only 5 had to be attempted. Marking scheme for multiple choice questions was +4 for correct response, -1 for incorrect response, 0 if not attempted. Marking scheme for numerical based questions was +4 for correct response, -1 for incorrect response and 0 in all other cases. Total marks of this section were 100.

JEE Main Exam 2023: Difficulty Level
Questions covered almost all chapters of Class XI & XII CBSE Board. It was a balanced paper.
Mathematics – Moderately Tough Level. Weightage was given to chapters of Algebra and Coordinate Geometry. Questions asked from Circles, Hyperbola, Definite Integrals, Limits, Differential Equations, Matrices, Binomial Theorem, Probability, Statistics, Permutation & Combination, Determinants, Vectors, 3D Geometry, Complex numbers, Progression Series. Both MCQs and Numerical Based questions required lengthy calculations. This section was Lengthy & Tough as per few students.
Physics – Easy level. Weightage given to chapters of Kinematics, Circular Motion, Laws of Motions, Gravitation, Heat & Thermodynamics, Wave Optics, Current Electricity, Electrostatics, AC Circuits, Modern Physics, Communication Systems, Semi-Conductors. Numerical based questions were reported as Easy. This section was balanced overall.
Chemistry –Easy to Moderate Level. Physical Chemistry was given less weightage as compared to Organic & Inorganic Chemistry. Questions asked from, d & f Block elements, Ores & Metallurgy, Environmental Chemistry, Chemistry in Everyday Life, Biomolecules, Aldehydes & Ketones, Amines, Ethers & Phenols, Aryl & Alkyl halides , Chemical Equilibrium, Atomic Structure, Solutions, Chemical Kinetics. MCQs were tricky compared to Numerical Section.
In terms of order of Difficulty – Maths was Moderately Tough, Chemistry was Easy to Moderate Level, while Physics was Easy. Overall, this paper was Moderate level as per students.
