JEE Main Jan 31 Analysis: The National Testing Agency (NTA) has increased the difficulty level of the Joint Entrance Examination Main (JEE Main) BTech, BE paper held today. The paper, as analysed by experts, is easy to moderate level. The maths section was lengthy and tricky in shift 1, while it was moderate in shift 2.

In the morning shift, NTA has increased the difficulty level of the January 31, 2024 paper in comparison to the one conducted on the January 30 morning shift, Ajay Sharma, national academic director, Engineering, Aakash BYJU’S said while analysing the JEE Main 2024 January 31 paper. 

“In the JEE Main 2024 January 31 morning shift paper, chemistry was somewhat of the easy to moderate level with some confusing questions in inorganic chemistry whereas mathematics had tricky and lengthy questions and can be considered to be moderate to difficult level by many students,” he added.  

The quality of the questions was good and the paper was a bit lengthy because of the maths part, students who appeared for the JEE Main January 31 morning session exam said.

The JEE Main paper 1 comprised three subjects – physics, chemistry and mathematics. The paper was held for a total of 300 marks.

Average students found mathematics difficult and chemistry confusing because of the inorganic chemistry section in the JEE Main January 31 morning session exam. The overall difficulty level of the paper, according to experts, can be said to be moderate to difficult. The difficulty level-wise order according to a large section of students is mathematics > chemistry > physics.

In terms of order of difficulty the shift 1 paper, Ramesh Batlish, Head-FIITJEE Noida Centres said, mathematics was moderate while chemistry was Easy. “Overall, the JEE Main 2024 January 31 paper was of moderate level as per students,” the FIITJEE expert said.

Most of the questions were theoretical in shift 1 with the maximum number of questions asked from organic and inorganic chemistry. Physical chemistry was asked very less in the exam. In physical chemistry, questions were asked from chapters like chemical kinetics and structure of atom. 

Questions from prominent organic and inorganic chapters like hydrocarbons, alcohol, phenol and ethers, general organic chemistry, d-block elements and chemical bonding were asked in the morning shift.

Organic Chemistry had around 10 questions in the second shift. Questions asked from GOC, alcohols, ether and phenols, amines, aldehydes and ketones, aryl and alkyl halides mixed concept questions, biomolecules. Physical Chemistry had questions from mole concept, thermodynamics, chemical kinetics and ionic equilibrium in the evening shift on January 31. Inorganic Chemistry had questions from coordination compounds, chemical bonding and periodicity. Some NCERT fact-based questions asked.

Almost all the questions are more or less related to or asked from NCERT only.

According to the feedback received from students, the physics part was of moderate level in the first shift. Questions from Gravitation, Newton’s laws of motion, kinematics, current electricity, modern physics and magnetism were duly represented in the paper. Most of the questions were asked from the Class 12 syllabus in the JEE Main morning shift.

Some good questions from kinematics, laws of motion, work power and energy, heat and thermodynamics, sound and waves, gravitation, electrostatics, optics, modern physics, semiconductors were asked in the second shift.

The mathematics paper was of a difficult level based on students’ feedback. The questions from calculus were dominant in the paper. The questions were also asked from Probability, Vectors, Determinants and Quadratic Equations were there in the morning shift paper. 

The maths paper in the afternoon shift was of easier level. Few MCQs and numerical-based questions had lengthy calculations and tricky.

Almost all the topics were covered in the first and second shift.
