How to calculate JEE Main 2024 Percentile Score: Know Normalization Process

The National Testing Agency (NTA) will announce JEE Main 2024 result in the form of percentile score. NTA uses the normalization formula to calculate the JEE Main percentile score of candidates. JEE Main percentile and normalization formula used by NTA (National Testing Agency) is provided here. To determine JEE Main 2024 results and rank list, NTA will adopt the process of normalization which is based on percentile calculation. The rank list of JEE Main 2024 will be prepared by the NTA based on percentile scores and not on the raw marks secured by aspirants in the exam.

How To Calculate JEE Main 2024 Percentile Score

JEE Main 2024 exam will be held on multiple days and sessions with the difficulty level of the exam varying from day to day and from session to session. Thus, to ensure equity in assessing the performance of all the test-takers, the exam conducting authority introduced the percentile system based on the normalization process. NTA uses the given below formula to calculate the percentile score of a candidate

Formula to calculate JEE Main percentile score of a candidate:

Key Terms For Calculating JEE Main 2024 Percentile Score

Before we delve deeper into how will NTA calculate the JEE Main 2024 Percentile Score through the Normalisation Process, there are some key terms you should know.

Key terms	What they mean
Percentile/ Percentile Score	Percentile Score is the score based on the relative performance of candidates who have appeared for the exam. To calculate a percentile score, the marks secured are converted into a scale ranging from 100 to 0 for each session of examinees. NOTE: Percentile score is not the same as the percentage of marks secured.
Normalisation	It is the practice of comparing candidates' scores who appeared in different shifts of the exam. The normalization process will be similar to the ones currently being adopted for other national level competitive exams like CAT.
Highest Raw Score and Percentile Score	All the highest raw scores will have a normalised Percentile Score of 100 for their respective session. This means, that the highest raw scores secured by candidates would be normalised to a 100 Percentile Score for their respective session.
Lowest Raw Score and Percentile Score	Percentile Score of all the lowest raw scores is different. In this case, the percentile score will depend on the total number of candidates who have taken the examination for their respective sessions.

Highlights of JEE Main 2024 Percentile Score

• JEE Main percentile score is the normalized score for the exam and not the raw marks of the test taker.
• The percentile score specifies the percentage of candidates who have scored equal to below (raw scores) a particular percentile in JEE Main. Thus, the topper of each session of JEE Main will get the same percentile i.e. 100.
• Percentiles will also be calculated and converted for marks obtained in between the highest and lowest scores
• The percentile score will be used to prepare JEE Main merit list
• The percentile scores for JEE Main will be calculated up to 7 decimal places to reduce tie-breaking scenarios and avoid the bunching effect
• The overall percentile is not the aggregate of the percentile of the individual subject

To help you understand how the agency will calculate JEE Main percentile score, here’s an example.

Example: In 2021, JEE Main was held in four sessions of test-takers where the days and shifts were allotted randomly to candidates.

• Session-1: Day-1 Shift-1    
• Session-2: Day-1 Shift-2   
• Session-3: Day-2 Shift-1
• Session-4: Day-2 Shift-2

The JEE Main test takers were distributed in the following manner:

Distribution of candidates
Session	Day/Shift	No of Candidates			Marks
		Absent	Appeared	Total	Highest	Lowest
Session-1	Day-1  Shift-1	3974	28012	31986	335	-39
Session-2	Day-1  Shift-2	6189	32541	38730	346	-38
Session-3	Day-2  Shift-1	6036	41326	47362	331	-49
Session-4	Day-2  Shift-2	9074	40603	49677	332	-44
Total(Session-1 to Session-4)		25273	142482	167755	346	-49

The above example of the distribution of candidates, the method to calculate the Highest Raw Score in each paper will be normalized to 100, thus indicating that 100% of candidates have obtained scores that are equal to or lesser than the highest scorer/ topper for that session.

Example: Highest Raw Score and Percentile Score

According to the official website of JEE Main, the Percentile Score of all the lowest raw scores will be different and will be based on the total number of test-takers for their respective sessions.

Highest Raw Score and Percentile Score

Session	Total  Candidates Appeared	Highest  Raw Score	Candidates who scored EQUAL OR LESS THAN Highest Raw Score	Percentile Score
Session-1	28012	335	28012	100.0000000 [(28012/28012)*100]
Session-2	32541	346	32541	100.0000000 [(32541/32541)*100]
Session-3	41326	331	41326	100.0000000 [(41326/41326)*100]

Lowest Raw Score and Percentile Score

Session	Total  Candidates Appeared	Lowest  Raw Score	Candidates who scored EQUAL OR LESS THAN Lowest Raw Score	Percentile Score
Session-1	28012	-39	1	0.0035699 [(1/28012)*100]
Session-2	32541	-38	1	0.0030730 [(1/32541)*100]
Session-3	41326	-49	1	0.0024198 [(1/41326)*100]

JEE Main 2024 Tie Breaker Rules

JEE Main merit list/rank list will be prepared based on the Percentile scores of the Total Raw Scores. In case, where two or more test takers secure equal Percentile Scores in the exam, the inter-se merit will be determined in the following order:

• Candidates obtaining higher Percentile Score in Mathematics in the Test.
• Candidates obtaining higher Percentile Score in Physics in the Test.
• Candidates obtaining higher Percentile Score in Chemistry in the Test.
• Candidates older in age to be preferred.  

Normalization Process To Prepare JEE Main 2024 Ranklist

NTA’s normalization process for the preparation of JEE Main merit/rank list will comprise of the following steps:

 

• Step-1: Refers to the conduct of the exam. JEE Main is conducted in two shifts over four days.  
• Step-2: Once the examination is over, the results for each session will be prepared using raw scores and percentile scores for each subject.
• Step-3: The third and last step would be the compilation of the NTA score and preparation of JEE Main merit list. Remember, the Final Ranking/ Merit would be prepared only after resolving ties (if any).

To compile JEE Main 2024 result, the four NTA scores (Physics, Chemistry, Mathematics, and overall score) of the first attempt and the second attempt will be merged for the compilation of results and preparation of the overall Merit List/Ranking. Candidates who appear in both the attempts; their best of the two NTA scores will be considered further for the preparation of Merit List /Ranking.
