Hii aspirant,

Yes you have to be physically be present during the document verification even if u are sick.The physical presence of the candidate is mandatory.

And for AIQ u have to go to the particular college and physical presence is necessary over there too. 

Hope the answer is helpful.

GOOD LUCK! 

yes you must go.For second round,I will state it clearly :

those wo have already had their documents verified in the first round are not required to undergo doc verification again.

those who didn't got their document verified in the first round and want to participate in the 2nd round should get their document verified now.

hope it helps!
