This is being done because the candidates have realised only ‘now’ that their documents have not met government requirements. And not meeting government requirements means losing an IIT seat.

PaGaLGuY confirmed this development with Prof KV Krishna, Chairman, JEE Advanced 2016, who admitted that students have been calling with queries on the subject of category. Category is nothing but division according to economic and reservation status.

The scenario of asking for changes
however is not as easy as it seems, precisely because
the forms have information submitted when they took the JEE Main Exam. Post that these candidates have qualified for Advanced on the
basis of the same forms.

Krishna clarified, “Wherever the conversions are possible, as per the
JEE Mains remarks, we will be able to take care of it. We will accept the
documents as per the declarations given on Advanced official website.”
