Analysis of JEE (Main) Paper 1 Jan 24, 2023, Morning Shift

The paper was of easy to moderate level. A few good questions were sprinkled here and there in the three subjects. A majority opinion was that the Physics part was the easiest, Whereas Chemistry was of easy to moderate levels. Mathematics was moderate. Chemistry was Memory Based while Maths was calculative but students were able to complete the paper in a given time. A subject-wise analysis in detail is given below:

Physics: Questions were set from covering all the topics. Students were tested on the simple level of applicability of concepts. Numericals were more in numbers than theoretical questions. Questions were from Thermodynamics, Electrostatics, Optics, Magnetism, Modern Physics and other chapters. Those students who have thoroughly covered the syllabus of XI and XII along with sufficient problem-solving through similar types of practice tests will score nicely in this paper.

Chemistry: The chemistry part was on predicted lines. It was observed by Students that the physical portion was less as compared to Organic and Inorganic Chemistry. All the questions from Organic Chemistry were asked in MCQ form. The whole paper was NCERT based. Chemistry in everyday life, GOC, Aldehydes, Ketones and Biomolecules are the chapters from which a significant number of questions were asked.

A thorough study of NCERT books, solving NCERT examples and practising through mock tests holds the key to success in this paper.

Mathematics: Mathematics part was a bit lengthy but Moderate. 5 to 6 questions from Calculus were the main stay of the paper. There were not less than 5 questions from Algebra, 2 questions from Coordinate Geometry and 2 or 3 questions from Trigonometry. Chapters like Vectors, 3D Geometry and Probability too found representation in this paper.

Practising a lot of mock tests would be a good strategy for the preparation of this paper.

Overall, it was a typical JEE (Main) paper of moderate difficulty level which can be solved comfortably in the stipulated time. Solving Archive questions helped students a lot. The order of difficulty in different subjects as assessed by a large section of aspirants is 

Mathematics > Chemistry > Physics.

It was a paper of Easy to Moderate level. Physics was the easiest of the lot whereas Mathematics because of some lengthy calculations were considered to be moderate by many students. A detailed subject-wise analysis is given below.

Chemistry

The paper was by and large based on NCERT books and examples. The majority of the numerical-based questions were from Physical Chemistry and the remaining from Organic and Inorganic Chemistry. Overall the questions from the Physical, Organic and Inorganic branches were more or less evenly distributed. Chemistry in everyday life was included in the paper. Questions from prominent chapters like coordination compounds, equilibrium, thermodynamics Redox reactions, Chemical bonding and Chemical Kinetics were asked. Overall coverage of the chapters was uniform. d-block and p-block had less weightage in the paper. A thorough study of the NCERT books, solving NCERT examples and mock tests based on NCERT is the guarantee of success in these types of tests.

Physics

According to a sizeable number of students, the Physics part was also of easy level. Questions from Optics, Waves and Modern Physics were duly represented in the paper. Around 3 to 4 questions from SHM, Three questions from Modern Physics and two questions. Electromagnetic Waves were there in the paper. Other chapters were also included in due proportions. There were a good number of numerals which were largely formula based. According to students XII Physics had more weightage on the paper. Archive questions were also there on the paper. Solving a good number of mock tests would prove to be an effective strategy.

Mathematics

The mathematics paper was moderate but slightly time taking due to the lengthy calculations involved. A few good questions were interspersed sporadically. Questions were asked from Calculus, Coordinate Geometry, Vectors & 3D and Algebra were there. Coordinate Geometry was dominant in the paper. Almost all the topics were covered. Again practice through mock tests holds the key.

Overall it was a balanced paper which can be solved in the stipulated time. According to the student questions, Only MCQ and Integer types but Numerical value questions were not there in contrast to the previous year. The difficulty level-wise order according to a cross-section of students is

Mathematics > Chemistry > Physics

Just following yesterday’s trend overall paper was easy to moderate. Good students were able to complete the paper in a given stipulated time. Doing previous year’s questions and attempting similar tests should fetch good marks.

I’ve included for you the detailed subjective analysis below.

Physics: According to a large number of students Physics part was easy. Questions were spread in all topics like Mechanics, Waves and Modern Physics. The optics part had less contribution in this shift. Match-type questions were also there. The paper was formula based and students were able to do questions easily.

Chemistry: Overall paper was of a moderate level. Study of NCERT books and mock tests based on NCERT holds the key to getting good marks. Physical Chemistry questions were fewer as compared to Organic Chemistry. Questions from chapters like Co-ordination Chemistry, Atomic Structure, Thermodynamics, Redox reactions, Chemical Kinetics, Hydrocarbon and Aldehyde and Ketones were there while questions from chapter Chemistry in Every-day life were conspicuously absent.

Mathematics: Mathematics paper was calculative and lengthy. Questions were spread around Calculus, Co-ordinate Geometry, 3D and Algebra. Around 4 to 5 questions were from Calculus, 3 to 4 questions from Co-ordinate Geometry and Binomial Theorem. Students were able to attempt question practice through mock tests holds the key.

Overall students found Maths papers very lengthy but not difficult. 

The order of difficulty subject-wise is
