Dear aspirant,

Exact percentile score cant be predicted as it varies from shift to shift . The marks vs percentile score cannot be predicted accurately. I can give you only a approximate range around which your percentile should lie. But again this can vary as these are according to my calculations.

So your percentile should be around 98.
