Dear aspirant,

As you have mentioned that you have got 68 marks in July 27th 2nd session and you want to know your percentile. So, I would like to tell you that it is a bit difficult to predict the exact percentile because it depends upon certain factors like number of candidates appearing in the examination, quality of the candidates, difficulty level of the paper

So, as per my view in this marks you would get around 80 percentile.
