Hello Manish

We can't actually predict the marks equivalent to 90 percentile but an estimate for the rank can be given.

The rank would approximately lie within 105,045-125,045 according to the formula given by our experts. Deviations may be possible from this range because actual number of students are not known now as there will be one more exam in April. 

Till now, as per our experts and past trends, percentile above 85 are supposed to qualify for next level.

All the best!!
