JEE Main Percentile & Normalization of Class 12th Board Marks

JEE Main 2016 All India Ranks have been announced. The ranks are used for admissions to NITs, IIITs and GFTIs across the country.  The percentile and normalization process of Class 12^th Board marks and JEE (Joint Entrance Examination) Main scores have always been a matter of concern for students appearing for the exam.

“What is percentile? How is it different from Percentage?” or “What do you mean by normalization”? are some of the common questions you get to hear from students.

Predict your JEE Main Percentile by using our JEE Main Rank Predictor.

So, let’s start with the basics:

Difference between Percentage and Percentile

The percentage of marks and percentile are totally different entities hence the candidates should not confuse with both the above terms. Here’s the difference.

Percentage	Percentile
Percentage is a number out of 100.	Percentile Score of a candidate in a Board or JEE (Main) will reflect how many Candidates have scored below that candidate in his/her Board or JEE (Main) Examination. A Percentile score is the value below which a certain percent of observations fall.
	Percentile Score of a candidate in a Board or JEE (Main) will reflect how many Candidates have scored below that candidate in his/her Board or JEE (Main) Examination.

 

What is Normalization?

Normalisation is the process of ensuring that students neither are benefitted nor receive any disadvantage by the difficulty of their Boards. The very process is used in other countries with similar issues as in India. 

The JEE Mains official website states, “A Percentile score is the value below which a certain percent of observations fall.” 

The website further explains:

40th Percentile is the value or score below which 40 Percent of the observations may be found. The percentile of a candidate will be calculated as:

100 X Number of candidates in the ‘group’ with aggregate marks less than the candidate / Total number of the candidates in the ’group’

Here is an example to help students understand the concept better:

Suppose in a particular Board, the number of candidates registered are 13918 and  the number of candidates who have actually appeared for the exam is 13711.

Example 1: An aspirant has scored 50% marks in his/her Board and 2218 aspirants have scored below him/her. Here is how the percentile will be calculated:

Percentile score for 50% marks in the Board =(2218 x 100)13711 = 16.18

Example 2: A candidate has scored 60% marks in his/her Board and 6865 students have scored below:

In this case, here is how the percentile will be calculated:

Percentile score for 60% marks in the Board = (6865 x 100)/13711 = 50.07

Example 3: A candidate acquires 90% marks in his/her Board and 13615 students score below him. In this case, here is how the percentile will be calculated:

Percentile score for 90% marks in the Board =  (13615 x 100)/13711 = 99.30

With the above mentioned examples, it can be determined that the percentage of marks acquired by an aspirant(50%, 60% or 90%) varies from the percentile score (16.18, 50.07 or 99.30).

Note 1: The normalized Qualifying examination marks will be based on the position of the candidate in the Board (i.e. his/her percentile score). The percentile score a candidate gets in his/her board will mainly contribute to his/her normalized marks.

Note 2: The candidates, willing to appear in the improvement examination to improve the qualifying examination marks, will have to appear in all the five subjects for improvement.

Here are the five subjects which will be taken into account for calculation of percentile and normalization of qualifying examination marks for paper 1(B.E./B. Tech.) and paper 2 (B. Arch./B. Planning)of JEE (Main):

• Language
• Physics
• Mathematics
• Any one of (Chemistry, Biology, Biotechnology, Technical Vocational Subject)
• Any other subject

Please note that if a candidate has appeared in six subjects in the qualifying examination, the subject (fifth or sixth) with better marks will be considered.

Note 3: In the percentile system, the total marks (of all five subjects) obtained/shown on the mark-sheet of a particular year are required in JEE (Main) and also in JEE (Advanced). The marks from two different years (i.e. marks for 3 subjects from year 2015 and marks for other 2 subjects from 2016) mark-sheets cannot be considered for percentile calculation.

To calculate the normalized qualifying examination marks, given below is the data required:

• Marks of all the students in that Board whose subject combinations meet the eligibility criteria of JEE-Main.
• Marks of all the students in JEE  Main 2016

Normalized Qualifying Examinations Marks:

Students should note that the normalized qualifying exam marks will be calculated on the basis of the candidate’s position in the Board exam(percentile score). The percentile that an aspirant scores will mainly contribute to his/her normalized marks.   

Detailed Normalization Process adopted for admission to NITs/IIITs/CFTIs on the Basis of Class 12th Qualifying examination marks:

• Ao = Aggregate marks obtained by each student in JEE Main 2016.
• Bo = Aggregate marks in a particular board computed from a list of five subjects meeting the JEE Main 2016 Eligibility Criteria. This is used to compile the percentile (P) of each student to get the corresponding JEE Main 2016 marks
• B1 = JEE Main 2016 aggregate marks corresponding to percentile (P) at the All- India level.
• B2 = JEE Main 2016 aggregate marks corresponding to percentile (P) among the set of aggregate scores obtained in the JEE Main 2016 by the students of that board.

Calculation of normalized board score of the candidate:

Bfinal = 0.5 * (B1 + B2)

Note: The JEE Main marks and the Normalized board marks will be used in the ratio of 60: 40 for admission to the CFTIs(Centrally Funded Technical Institutes).

To derive the JEE Main 2016 merit list, the composite score is calculated in the following way:

C = 0.6 * AO + 0.4 * Bfinal

The composite score, thus, calculated will be the basis to calculate the JEE Main 2016 Merit Ranks.
