Query regarding supply of certified answer books

As institute has said that they would not provide physical copies of cert ans books, but they will be hosted ... as said on this website https://www.icai.org/new_post.html?post_id=10437&c_id=219 Then my query is it says "They can view and take print out of the scanned copies of the answer books sought by them, at their convenience, but not later than 10 days from the date of hosting" so can we not download it as pdf??? and next query is if we found some marks to be changed then there is time of 30 days to state institue.... will it be available now? from which date? plz clear this point....
