I passed 10th from NIOS on 2007,but I lost all my NIOS documents except my ID card.Now I want to give 12th from NIOS but for admission on 12th I will need the documents I guess.

So what should I do now?
I know that I can issue duplicate documents,I just downloaded the application form ,but its for many documents,which documents will I need to get admission in 12th NIOS,will I be needing the passing certificate I am asking this because in the form its says for duplicate passing certificate an affidavit executed in front of a 1st class magistrate will be needed which is a bit time consuming.

Please help

Thanks everybody
