How to calculate JEE Main 2021 percentile score?
National Testing Agency or NTA reintroduced the system of percentile scores for the Joint Entrance Exam (JEE Main) in 2019 and has often been a matter of confusion amongst students taking the exams for the first time. Here is how you can find an approximated percentile score through your raw marks and a briefing on the normalization process followed by NTA.
How to calculate JEE Main percentile score?
The percentile scores issued by NTA are an indication of the relative performance of a student to the other candidates and not the percentage marks of an individual. It is measured on a scale of 0 to 100. The student who scores the highest amongst all gets a 100 percentile and others are relatively scored.
One can calculate the percentile with the following formula:
The process of normalization based on percentile score.
The National Testing Agency conducts the exams in several shifts and there is a possibility that the question papers the students are answering might be of varying difficulty for every shift, hence to ensure fair scoring NTA adopted the Normalization procedure.
It is an established procedure where the marks of candidates are compared across various sessions and NTA uses percentile equivalence as a standard of comparison.
Percentile scores are the normalized scores for the examinations and is used to create the merit lists.
How NTA resolves ties using percentile scores?
NTA rounds off the percentile scores of the candidates to 7 digits to reduce ties and decrease the bunching effect.
Even then if a tie happens NTA checks the following criteria respectively to resolve the tie.
1. Higher percentile score in Mathematics.
2. Higher percentile score in Physics.
3. Higher percentile score in Chemistry
4. Candidates older in age.
The percentile of the mentioned subjects can be calculated by the following method:
Given,
T1, M1, P1, C1 be the raw scores in Total, Mathematics, Physics, Chemistry of a candidate and T1P, M1P, P1P, C1Pbe the Percentile Scores of Total, Mathematics, Physics, Chemistry of that candidate.
How NTA prepares rank list?
Step 1. Examinees are distributed in two days and two shifts per day.
Students are distributed in a total of 4 sessions.
Session 1: Day 1, Shift 1.
Session 2: Day 1, Shift 2.
Session 3: Day 2, Shift 1.
Session 4: Day 2, Shift 2.
Step 2. Preparation of results for each session.
The results are prepared in two forms.
· Raw scores.
· Separate percentile scores for Mathematics, Chemistry, and Physics.
Step 3. Compilation of NTA scores and preparation of the merit list.
The scores for all three subjects from the four shifts are merged.
For example,
The counselling for admission in various institutes and selection for JEE Advanced is based on this merit list.
We hope this article helped you understand the normalization procedure followed by NTA and helps you prepare better for the upcoming JEE Main exams.
