Top 20 percentile cut off- for Improvement
In case the candidate writes any subjects for improvement, there are some specific guidelines regarding the cut off marks. To clarify this, let’s consider two scenarios:
1. The candidate passes Class 12 Board Exam in 2018 but repeats one or a few subjects in 2019 for improvement or any other reason.
In this case, the academic eligibility is checked by considering the:
* Top 20 percentile cut-off for 2018
* Maximum marks obtained in the required subjects
2. The candidate passes Class 12 Board Exam in 2018 but writes all the subjects in 2019.
In this case, the best of the both years performances will be considered.
Top 20 percentile cut off marks- additional guidelines
Candidates should know these additional guidelines. This is for special situations like when the Board gives letter grade or aggregate marks. This is discussed in detail below.
What if your Class 12 Board awards only letter grades?
What if only letter grades are provided by your Board without giving any equivalent percentage of marks on the grade sheet? Then you should get a certificate from your Board specifying the equivalent marks. This certificate should be submitted at the time of seat acceptance. If you fail to produce this certificate, then the final decision will be taken by the CSAB/ JoSAA.
What if the Board provides the aggregate marks of both class 11th and 12th Board exams?
In this case, only the class 12 marks will be considered for verifying the academic eligibility. Likewise, the candidates marks in the last two semesters will be considered if the Board has semester system.
What if the School Board gives aggregate marks for all subjects?
Sometimes, marks for individual subjects are not given by the Board. Then the aggregate marks will be considered to verify if the candidate has the minimum qualifying marks in Class 12 for JEE.
What if the Board does not give the top 20 percentile cut off marks?
In some cases, the School Board may not give the top 20 percentile cut off marks. Then the candidate will have to provide a certificate from the Board which states that he/she falls within the top 20 percentile cut off. If the certificate is not produced, then the CBSE minimum qualifying marks will be used.
When to produce Class 12 mark sheet to check eligibility?
Candidates should produce Class 12 mark sheet to prove academic eligibility. It should be done during counseling for admission in IITs/NITs/IIITs and other CFTIs. It is not required during JEE Main Registration/ Application. In previous years, weightage of class 12th marks was considered for calculating JEE Main ranks. However, starting 2018, JEE Main ranks will be based solely on the JEE Main score.
What is percentile & how is it calculated?
Don’t confuse percentile with percentage. See how JEE percentile is calculated. For details, please check: How to calculate JEE Main percentile of Class 12 marks?
In summary, tor admission in IITs/NITs/IIITs and other CFTIs, the candidates should check the minimum qualifying marks in Class 12. One should check the top 20 Percentile cut off marks, category wise, for the respective Board, and for the particular academic year.
