The complete information regarding Jee advance is as follows:-
Top 1,50,000 candidates (including all 
categories) out of the qualifying candidates in Paper - I of JEE (Main) -
 2014 will be eligible to appear for JEE (Advanced) - 2014.Admission IITs will be based only on category wise All India Rank (AIR) in JEE (Advanced)2014, under the condition that such candidates are in the top 20 percentile of successful candidates of their respective Boards (or equivalent examination) in their respective categories.


1.If the Board does not provide the information regarding the same, the 
candidate will have to produce a certificate from the concerned Board 
stating that he/she falls within the top 20 percentile. 

2.If the candidate fails to do so, then the CBSE percentile will be used as the criteria for deciding minimum percentage of marks in the qualifying examination. 

3.If the 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 counselling. 

In case such a certificate is not provided the decision taken by the
 Joint Implementation Committee (JIC) of JEE (Advanced) - 2014 will be 
final.
