Analysis

JEE (Main) - 2018 had one paper; and had three parts - Chemistry, Maths

and Physics. In each part there are 30 questions carries 4marks each and for

wrongly attempted question minus 1 mark will be awarded. Finally paper

contains 90 questions and maximum marks for the paper is 360. Time

duration is 3 hr. There is a jumbling not only in the questions but also in the

order of the subjects .

It is also evident that the difficulty level of the question paper in

JEE (Main) - 2018 has increased moderately when compared with JEE(Main)-

2017. But several other state students feel it as much difficult when compared

with JEE(Main)-2017.

The question paper setters were given guidelines to frame questions in

such a way that at least 30% of the questions can be attempted by any

candidate with good preparation for the board examination and also has

Knowledge of Board practicals.

In JEE(Main)-2018 as well as in previous JEE exams, the question

paper is divided among the three subjects, Chemistry appears first, followed

by Maths and Physics also order had changed according to the code

assigned on it.

Analysis of the number of questions attempted by the students in this

Paper shows that maximum numbers of un-attempted questions are invariably

in MATHS/CHEMISTRY followed by PHYSICS.

This is due to the paucity in time available to the student. Considering the

fact that quantitative skills are an extremely important component of the

testing process, Mathematics section was outline with this expectation.

In Mathematics nearly about 15 questions are direct and simple. Previous

years Jee-Advanced Questions were repeated in JEE-Main-2018.

Among all the papers the extent of difficulty is more in CHEMISTRY, next is

MATHEMATICS and PHYSICS. Questions in MATHS/CHEMISTRY are more

analytically lengthy oriented with creates some confusion in the minds of the

students.
