## ABOUT PERCENTILE CALCULATION OF MARKS OF CLASS 12TH/QUALIFYING EXAMINATION

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 will reflect how many Candidates have scored below that candidate in his/her Board 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

**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

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

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

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

1- Language, 2. Physics, 3. Mathematics,

4-Any one of (Chemistry, Biology, Biotechnology, Technical Vocational Subject),

5- Any other subject.

Note: If a candidate has appeared in six subjects in the qualifying examination, the subject (fifth or sixth) with better marks will be considered.

5. For calculation of percentile of qualifying examination marks, for paper 2 (B. Arch./B. Planning) of JEE (Main), the marks obtained in following subjects will be considered:

1- Mathematics 2. Other four subjects.

6. For calculation of the total marks for five subjects, if the marks awarded in a subject is NOT out of 100, then the marks will be scaled (up or down) to 100 so that the total aggregate marks is out of 500.

7. For candidates who appeared in the Class XII (or equivalent) Board examination in 2017 but reappeared in 2018, the best of the two performances will be considered.

8. If a Board awards only letter grades without providing an equivalent percentage of marks on the grade sheet, the candidate should obtain a certificate from the Board specifying the equivalent marks and submit it at the time of acceptance of the allocated seat. In case such a certificate is not provided, the decision taken by the CSAB/JoSAA will be final.

9. If a Board gives aggregate marks considering both Class XI and Class XII examinations (in the 10+2 system), then only Class XII marks will be considered. Similarly, for Boards which follow a semester system, the marks scored in the final two semesters will be considered.

10. If a Board does not give marks scored in individual subjects but gives only the aggregate marks, then the aggregate marks given by the Board will be considered as such.

11. The category-wise cut-off marks for the top 20 percentile are calculated based on the marks scored by all the “successful” candidates in their respective boards in the particular year.

12. The cut-off marks for PwD candidates will be the same as the lowest of the cut-off marks for GEN, OBC-NCL, SC and ST categories.

13. It is reiterated that top 20 percentile cut-off for the academic year 2018 will be considered for the candidates who pass the Class XII (or equivalent) examination in 2018.

14. Similarly, top 20 percentile cut-off for the academic year 2017 will be considered for the candidates who pass the Class XII (or equivalent) examination in 2017.

15. If a candidate passes Class XII in 2017 but writes one or a few subjects in 2018 for improvement or any other reason, then top 20 percentile cut-off for 2017 will be considered. However, if a candidate writes all the subjects in 2018, then the best of the two performances will be considered.

16. In case a Board does not provide information about the cut-off for the top 20 percentile, the candidate will have to produce a certificate from the respective Board stating that he/she falls within the top 20 percentile of successful candidates. If the candidate fails to do so, then the cut-off marks for the CBSE will be used.

17. If a candidate passes Class XII (or equivalent) in 2017, but writes any of the required subjects (mentioned above) in 2018 for improvement or any other reason, then the aggregate percentage will be calculated by considering the maximum marks obtained in the required subjects.
