The JEE main 2019 exam dates are 8th, 9th, 10th and 12th of April. Unlike previous years this year, the JEE mains is conducted by NTA (National Testing Agency) and not by CBSE. Two shifts per day hold it. So, by now six sessions of exams are over, and we will be going all over those JEE exam paper and analyze them. The general trend of this year’s paper is physics being tough and mathematics being moderate and chemistry being reasonably easy but timeconsuming.
JEE Main analysis 2019 – Students Reaction
8th April Shift 1
According to students, the APRIL exam was similar to that of the January one or the JEE main previous year question paper, and the difficulty level was comparable to that examination. Most students have an opinion that the physics paper was the toughest of all the three followed by mathematics and chemistry. The portions were more taken from the 10+1 parts than from the 10+2 parts. When asked about how the portions were covered all the sections almost had equal weightage.
Some students also say that all the three sections were of equal difficulty and Paper was moderately difficult. Mathematics had questions from limits and derivatives and some questions from quadratic equations. In physics, there were some questions from mechanics, few from optics and E.M. waves. Inorganic chemistry had no reactionbased questions and was pretty easy.

8^{th }April Shift 2
In the examination, students feel mathematics was pretty , and physics comes second. Calculus had tough questions which took some time to solve. Physics had most questions from 11th, and 12th portion had some direct questions. When compared to January examination students claim January session was more comfortable than this examination.
Some students feel the physics section was pretty easy and had some questions from gravitation. Mathematics was pretty tough, and chemistry was moderate with a lot of questions from inorganic chemistry.

Students feel that mathematics was more stringent than the rest of the subjects. The examination was similar to January one. Chemistry had an easy question than physics and Mathematics
Others feel that the April section was more comfortable than the January exam. They feel mathematics was the most robust section and physics was pretty easy. Physics had a lot of questions from mechanics, semiconductors, and electrostatics.
Most students feel the exam paper was smooth and they might cross the JEE main cut off and ace the examination.

Students feel chemistry was the easiest of the three sections and inorganic chemistry had a lot of questions in it. Physics questions were pretty tough and were both applications based, and some were tricky and calculation based. Mathematics had most questions from Coordinate geometry and trigonometry. Also, they feel some questions were similar to previous years questions. Most questions were NCERT based. Compared to the January examination students feel that This time the exam was tougher than the previous one.
Some students felt mathematics was most comfortable of all and it covered almost all the chapters. At least one question was asked from each chapter they claim. Most students suggest that students who are about to write the exam impart more focus on physics as all the students feel physics was the toughest subject. No student was seen to complain about lack of time, so the paper was not timeconsuming.

10^{th} April Shift 1
Most students say the difficulty level of the examination was moderate and chemistry, as usual, was the easiest of the three sections. Physics and Mathematics were moderately difficult according to some students. Mathematics had questions out of NCERT textbooks, and some of them were tricky and twisted. Some students feel the question was pretty lengthy. When asked about previous years examination students say that this examination was more accessible than the January one and the last year’s examination.
Other students feel that in mathematics integration and differentiation had some problematic question. They also continued to say that both 11th and 12th had an equal number of questions so preparing students should concentrate on both the portions.

Students feel the examination was of moderate difficulty. Chemistry as usual was easiest of them all. Chemistry had fewer questions from organic, and most questions were from inorganic chemistry. Physics was the most difficult.
Some students feel organic chemistry had a good number of questions and some questions came from polymers. Mathematics had questions from vectors, limits and statistics. Students who wrote the January session also claim both examinations were of similar difficulty and no questions seem to be repeated. Students feel the new online mode of examination is more comfortable and simpler.

Expert Analysis
The Following expert analyses of each session of the April JEE main examination will contain contents such as number of questions in each difficulty levels, number of questions from each chapter and portions and comparisons of the examination with the JEE main January sessions.
According to experts, the April exam is almost of the same difficulty as that of the January exam. Nearly 70% of questions were directly from NCERT.
Experts claim that 46% questions were from 11th class and rest 54 % were from 12th classes discussing the questions and their difficulty levels,
For chemistry, 13.3% of the problems were tough, 33.3% were of moderate difficulty and 53.3% questions very easy. When compared to the January examination for which almost 7% questions were tough,50 % were moderate and the rest 43% were pretty easy questions. Hence as January has more percentage of easy questions, April paper was slightly more difficult than before.
For mathematics, 10 % of the questions were tough, 60% were moderate, and 30% were easy questions.
And for Physics 6.7% of questions were pretty tricky, 56.7% were moderately tricky and 36.7% questions straightforward.

8^{th}April Shift 2 Expert Analysis
When compared with the January JEE main papers 8th April shift2 paper was easier and had fewer questions with very high difficulty.
Physics:
Portions like Semiconductors and communication systems, Thermal properties of matter, calorimetry, Units, and dimensions had stricter questions than the January session’s papers. Parts like Centre of mass, Classical magnetism, Gravitation, Magnetic effects of electric current, Oscillations and SHM, Photoelectric effects and Electromagnetic waves had questions that comparatively easier than January. Laws of thermodynamics, motion in onedimension, Newton’s laws of motion, Nuclear Physics and radioactivity questions were elementary compared to previous examinations.

9^{th}April Shift 2 Expert analysis
Experts have an opinion that compared to the January session Physics section is easier in the April session. Chemistry has gotten a little bit more difficult, but mathematics questions were more straightforward than the January session of JEE main.
Chapter wise difficulty comparison was made for January and the April 9th exam.
For physics chapters like modern physics, gravitation, semiconductors and communication systems, Work Power Energy and Motion in One dimension has easier questions than January sessions. But chapters like Current electricity, experimental physics, Properties of matter and Fluid mechanics had tougher questions than the January paper. Chapters like Wave optics, Circular motion, magnetic effects of current, oscillations and SHM had no questions asked from them.
When chemistry was considered, chapter like carboxylic acid, ionic equilibrium, Atomic structure, Chemical bonding and atomic structure, d and f block elements were tougher than the January sessions of the JEE main. But chapters like Haloalkenes, electrochemistry, Amines and diazonium salts and environmental and practical chemistry has gotten easier when compared to the January papers. Portions like esters and ethers, aromatic compounds, chemical equilibrium, nuclear and surface chemistry, redox reactions and volumetric chemistry and Solid states saw no questions in the Shift 2 of April 9th JEE main examination.
In Mathematics, Complex numbers, Definite integration and parabolas had tough questions compared to January session’s papers but portions like Functions, Mathematical reasoning, Statistics and Sequences and series had easier questions than January session. Parts like Differential coefficient, hyperbola, probability, Vectors, Mathematical induction had no questions in this paper.
