Creating buzz amongst engineering aspirants, the percentile and normalization process of Class 12
th Board marks and JEE(Joint Entrance Examination) Mains scores has been a topic of much concern for the students.
One of the most common questions asked by aspirants is the difference
between percentage and percentile. Factually, the percentage of marks
and percentile are two totally different entities.
Percentage, is a number out of 100, while percentile or a percentile
score of an aspirant in JEE Main or Board basically reflects the number
of candidates who have scored below that candidate in their Board exams
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.
Understanding the Percentile score/system:
As the JEE Mains official website states, “ A Percentile score is the value below which a certain percent of observations fall.”
Explaining the system further, the site quotes an example mentioned below:
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 make the concept clearer to students:
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. In this case,
the percentile will for this candidate will be calculated as follows:
Percentile score for 50% marks in the Board =(2218 x 100)13711 = 16.18
Example 2: An aspirant scores 60% marks in his/her Board and 6865 students have scored below:
Him in the exam. In this case, the percentile score will be calculated in the below manner:
Percentile score for 60% marks in the Board = (6865 x 100)/13711 = 50.07
Example 3: An aspirant acquires 90% marks in his/her
Board and 13615 students score below him. The percentile score will be
calculated in the following way:
Percentile score for 90% marks in the Board = (13615 x 100)/13711 = 99.30
Thus, the above mentioned examples indicate 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).
Subjects considered for the Percentile score:
- 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.
Data considered to calculate normalized score for qualifying examination marks:
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) – 2014
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.
Points to note:
- Aspirants willing to appear in the improvement examination to
improve the qualifying examination marks, will have to appear in all the
five subjects mentioned above for improvement.
- 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 2012 and marks for other 2
subjects from 2013) mark-sheets cannot be considered for percentile
calculation.
- Candidates who are appearing in the improvement examination to
improve their qualifying examination marks will get only one chance to
inform JEE (Main) Unit as to which year qualifying examination marks to
be considered for the purpose of declaration of final merit.
JEE Advanced 2014:
1. For JEE Advanced, if an aspirant submits the particulars of
his/her qualifying examination for 2013, the top 20 percentile criteria
of 2013 will be applicable which was declared by IITs after the
declaration of the boards’ results of 2013. Similarly, the candidates
who are providing their qualifying examination particulars of 2014, the
criteria of 20 percentile will be applicable which will be declared
after the declaration of the boards’ results of 2014.
2. The weightage of normalized qualifying examination marks is only
for deciding ranking of JEE (Main) which will be used for admission to
all Centrally Funded Technical Institutions (CFTIs)/ NITs/IIITs but
excluding IITs.
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 2014.
- Bo = Aggregate marks in a particular board computed
from a list of five subjects meeting the JEE Main 2014 Eligibility
Criteria. This is used to compile the percentile (P) of each student to
get the corresponding JEE Main 2014 marks
- B1 = JEE Main 2014 aggregate marks corresponding to percentile (P) at the All- India level.
- B2 = JEE Main 2014 aggregate marks corresponding to
percentile (P) among the set of aggregate scores obtained in the JEE
Main 2014 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 2014 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 2014 Merit Ranks.
