JEE (Main) 2023 Paper-I for BE/B.Tech aspirants was held on 15th April 2023. Questions were asked from almost all the chapters of CBSE Board Class XI and XII. It was a balanced paper. In order of difficulty – Mathematics was moderate while Physics was said to be easy. Overall, this paper was of moderate level according to the students

** The paper had three parts and each part had two sections:**

Part-I- Physics had total 30 questions – Section-I had 20 multiple choice questions with single correct answer and Part-II had 10 numerical based questions out of which only 5 were to be attempted. The marking scheme for multiple choice questions was +4 for correct response, -1 for incorrect response and 0 for not attempting. The marking scheme for numerical based questions was +4 for correct response and 0 in all other cases. The total marks of this section were 100.

Part II- Chemistry had total 30 questions – Section-I had 20 multiple choice questions with single correct answer and Section-II had 10 numerical based questions out of which only 5 were to be attempted. The marking scheme for multiple choice questions was +4 for correct response, -1 for incorrect response and 0 for not attempting. The marking scheme for numerical based questions was +4 for correct response, -1 for incorrect response and 0 in all other cases. The total marks of this section were 100.

Part III- Mathematics had total 30 questions – Section-I had 20 multiple choice questions with single correct answer and Section-II had 10 numerical based questions out of which only 5 were to be attempted. The marking scheme for multiple choice questions was +4 for correct response, -1 for incorrect response and 0 for not attempting. The marking scheme for numerical based questions was +4 for correct response, -1 for incorrect response and 0 in all other cases. The total marks of this section were 100.

**Difficulty level as per the feedback received from the students on 15th April 2023 (Afternoon Session).**

Mathematics – Intermediate level. Weightage was given to the chapters of Algebra and Calculus. In Calculus, questions were asked from Functions, Limits and Continuity, Application of Derivatives, Definite Integrals, Area under Curves, and Differential Equations. In Algebra – Matrices, Permutations and Combinations, Vectors, Multiple Choice Questions in 3D Geometry, Progression, Statistics, Binomial Theorem, Mathematical Reasoning and Probability. Co-ordinate Geometry – Parabola, Circles and Ellipse had mixed concept questions. Both MCQ and numerical based questions require lengthy calculations. According to some students this section was also difficult.

Physics – Easy Level. Questions asked from Kinematics, Laws of Motion, Work, Power and Energy, Heat and Thermodynamics, SHM, Current Electricity, Magnetism, Gravitation, Modern Physics, Semiconductor, Communication Systems and Optics. Numerical based questions were rated as easy to moderate. More weightage is given to Class XII chapters.

Chemistry – Easy to Moderate level. Inorganic Chemistry had more questions than Organic and Physical Chemistry. The numerical section had questions from Chemical Kinetics, Electrochemistry and Ionic Equilibrium. Organic Chemistry had mixed concept questions from Amines, Alcohols, Ethers and Phenols, Biomolecules, Polymers and Aryl and Alkyl Halides. In Inorganic Chemistry there were questions from s-block, p-block, chemical bonding, co-ordination compounds, ores and metallurgy. Fact based questions were asked in this section.
