JEE Mains 2018 paper analysis: Experts who have analysed the paper found that it had a moderate difficulty level
JEE Mains 2018 paper analysis: The Central Board of
Secondary Education (CBSE) conducted the Indian Institutes of Technology
Joint Entrance Examination (IIT JEE) main exam on Sunday, April 8,
2017. As per experts, Paper I difficulty level was moderate, however,
students have found Physics section tricky and tough and Maths paper
lenghty.
The pattern followed this year was quite similar that of the last two
years’ papers. This year, close to 11 lakh candidates have appeared for
the examinations, as per reports. Out of which, only 2.24 lakh students
will be eligible for appearing in the JEE Advanced 2018 exam which is
scheduled on the May 20. The answer keys will be uploaded on the
official website, jeemain.nic.in, from April 24 to April 27, 2018.
JEE Mains 2018 paper analysis: Experts reactions
While some experts believe that the overall difficulty level was
moderate, some find few questions tricky. Here are analysis from top
coaching institutes.
Aakash Institute
Overall, the JEE Main 2018 was slightly on the difficult side. A few
questions in the paper were straightforward and could be solved by a
student who has been preparing sincerely for the exam. But a large
numbers of questions required lengthy solutions. A few questions were
difficult which will play crucial role to get top scores.
In all the three subjects, 5-6 questions were framed quite
differently. However, there was no ambiguous question in the paper this
year.
In Physics paper, overall questions were slightly on the difficult
side compared to last year. By and large, paper was on the expected
lines with few elements of surprise. Almost all the topics were covered
as prescribed by CBSE for JEE Main.
The Mathematics paper overall was slightly on the difficult side.
There were seven to eight lengthy questions, but a few questions were
straightforward as well. Questions were asked from all chapters.
Questions asked were conceptual and nearer to the JEE Advanced paper in
terms of tricks and approach. Students whose study was confined to NCERT
and related text books would find it difficult. Equal weightage was
given to Class 11 and 12 syllabus.
In Chemistry, almost equal weightage of Physical, Organic and
Inorganic Chemistry was there. Paper has average difficulty level. No
question was asked from the topics of Structure of atom, d &
f-block, Aldehyde Ketone, s-block, Polymer & Surface Chemistry.
Overall paper was balanced and mixture of conceptual and numerical
questions.

“In terms of difficulty level, this year’s paper was similar to the
last two years’ papers. The paper was moderately easy. A student should
not have had much trouble completing the paper as well. They found
similarities between the weightage of marks in this paper, and the 12th
standard syllabus. The JEE Main cut off should fall between 95 and 105.
Physics
Surprisingly, Physics was the toughest paper among the three. The
questions were a mix of theory based and calculation. This section was
not lengthy. There were 17 questions from 12th standard syllabus and 13
questions from 11th standard syllabus. This section had 4 difficult
questions, 20 moderate questions and 6 easy questions. Initial
assessment fond that none of the options of Q.6 of set B were correct.
The question was based on Pulley where minimum mass was to be
ascertained.
Chemistry
Chemistry was the moderately easy among the three. This section was
lengthy in comparison to the other sections. There were 14 questions
asked from 12th standard syllabus and 16 questions from 11th standard
syllabus. This section had 3 difficult questions, 17 moderate questions,
and 10 easy questions. Initial assessment suspects students may find 2
options of Q.63 of Set B could to be correct. However, we think the
answer should be option 1. This was a question from Alcohol phenol and
ether, on a reaction of Phenol.
Mathematics
Surprisingly, Mathematics was the easiest paper amongst the three.
Most questions were calculative. There were 10 questions asked from 12th
standard syllabus and 20 questions from 11th standard syllabus. This
section had 3 difficult questions, 14 moderate questions and 13 easy
questions.”
Prof Uday Nath Mishra, Chief Academic Officer, BasicFirst
“Expected cut off is 80(+-5%) marks out of 360. The paper was
moderate and based on NCERT. Chemistry was the most lengthy. Organic
chemistry was found more difficult, Physical chemistry was more
numerical based, whereas, Inorganic chemistry was easy. Maths was mostly
based on class 12 syllabus and was more formula based. Maximum
questions were from Calculus. Physics was based on class 11th syllabus
and greater portion of Mechanics & Electrostatics was covered.”
As per BASE institute, Physics was difficult in the overall
comparison. It was lenghty as well. Four questions are modified version
of those that appeared in the previous years JEE Advanced. This time,
equal weightage has been given to first and second year topics
Mr Ajay Antony, National Course director JEE Exam, T.I.M.E
The JEE Main off-line Examination of 2018 was held on 8th April. It
was a 3 hour paper, which started at 9:30am. The test paper had 90
questions for 360 marks. There were 3 parts in the question paper
consisting of Physics, Chemistry and Mathematics. The order of subjects
were different in different versions of the booklets. The options given
for the questions were also shuffled in various versions.
Each subject carried 30 questions. All questions were objective in
nature with 4 choices and there was only one correct response. Each
question carried 4 marks for the correct response and -1 for wrong
response. All questions were ‘Single Correct Multiple Choice’ type.
Physics and Chemistry questions were relatively easy in JEE Main
2018. The questions in Mathematics required lengthy calculations in
solving them. Hence, many students rated Mathematics section as ‘tough’.
