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.
While some experts believe that the overall difficulty level was moderate, some find few questions tricky. Here are analysis from top coaching institutes.
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.
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 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.
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.”

“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

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’.
