Percentile and Normalization marks class 12 / Qualifying exam

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

2. Percentage is a number out of 100.

3. 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. For example, the 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’

Example:  Suppose in a particular Board:

No of Candidates Registered =13918 and No of Candidates Appeared = 13711

a. A Candidate who has scored 50% marks in the Board and 2218 candidates have scored below him; his Percentile score will be calculated as follows

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

b. A Candidate who has scored 60% marks in the Board and 6865 candidates have scored below him; his Percentile score will be calculated as follows

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

c. A Candidate who has scored 90% marks in the Board and 13615 candidates have scored below him; his Percentile score will be calculated as follows

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

With these examples, it is clear that percentage of marks obtained by a candidate (50%, 60% or 90%) is different from the percentile score (16.18, 50.07 or 99.30).

4. 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.

5. 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.

6. 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.
