All You Need to Know

This year, JEE has changed the pattern for recruiting the best minds from across the country for the prestigious IITs & other government & private engineering colleges. JEE is being conducted by the newly formed testing agency, NTA (National Testing Agency). Instead of marks, the structure of assessment has shifted to a percentile-based system, where the percentile of best two subjects is considered out of 3; and the best of two exams is picked up while collating the scores and ranks.

This process has been put in place to ensure that those students who get a tougher set of questions are also able to secure ranks that will make them eligible for admission into prestigious institutes in the same capacity as their peers. According to experts, this year, the test-takers got the same paper, but the sequence of questions was different. Even the multiple-choice questions were jumbled up.

The JEE Main 2019 ranks are based on the percentile scores achieved by the students in both the sessions. This process, known as normalisation, leads to a better chance for students to crack the examination and score higher. It denotes the percentage of candidates, who have scored equal to, or below, that particular percentile in the examination.

So, the 15 toppers are students who have all got the highest score(100 percentile) after normalisation in their respective sessions. The marks obtained in between the highest and lowest scores have also been converted to the relevant percentiles.

A predefined formula for normalization is used to prepare the merit list of JEE Main. To understand it better, candidates should know few terminologies, like raw score, percentile score, subject percentile score, overall percentile score, and merit list first.

The NTA will calculate raw scores on the basis of the JEE Main marking scheme. For each correct answer by a candidate, 4 marks are allotted, and for each incorrect answer, there is a penalty of 1 mark. The goal of this exercise is to have a rational & transparent system of scoring to help students perform better.


The paper has been divided into two parts, i.e., Paper 1 & Paper 2. The first paper is a computer-based test, while the second is a mix, with some of its portions to be attempted in pen-paper mode.

The NTA has released the JEE Main results for Paper 1, based on which admissions to graduate programs of B.E. and B.Tech. would be initiated in engineering colleges.

The results for Paper 2 will be used for admission in B.Arch. & B.Planning; and will be announced later.


The percentile score in JEE Main results indicates the percentage of candidates who have scored equal to, or below, that particular percentile in that session. The formula to calculate your score is mentioned below:

Percentile Score of a Candidate = 100 X[No. of candidates who secured a raw score (or actual score) equal to, or less than, the candidate) ÷ (Total no. of candidates who appeared in that session)


The marks obtained by each candidate for all correct answers for each subject (Maths, Physics, and Chemistry) will be summed up to arrive at the raw score.


To understand, let us consider the January session of JEE Main 2019. As per the results statistics declared by the NTA, 8,74,469 students appeared for the exam across four days, with two sessions each (making it a total of 8sessions). Thus, the formula for calculating JEE 2019 rank for the January session is:[(100-NTA percentile score) X 8,74,469]÷100. For example, if the NTA percentile score is 90.7 then the JEE rank will be [(100-90.7) X 8,74,469]÷100=81,325.


The first attempt has been conducted in 4 sessions in total, with one session daily, divided into two shifts through which the raw scores & percentile scores would be collated. The final NTA score will be compiled using this data for preparing merit list/ranking. The scores are based on the relative performance of all those students, who appeared for the examination in one session.

The next online application for JEE Main April 2019 exam will start from February 8; and will remain open till March 7, 2019 for the computer-based test (CBT) scheduled between April 6 and 20, 2019.
