Class : Class 8
There is no second level in ieo,so chill.Now if you want to get a good ranking you should try to get a marks above 45.
And in the rest of olympiads,it depends on the question you answered.Like if have answered a question that ha been answered
correct by very less percentage , then you get a better rank.
But the first is you need to get a minimum of 40marks.
and alsp there are cutoffs.

It's different for all the subjects. For IMO it was 43 , for NSO 37.
We will get to know the cutoff only after the olympiad :)
