Even I am in class 10....I take coaching from FIITJEE...Based on their data they are expecting the top 20-25 to quality..My rank is 17 based on scores of my peers there and score is 166..The topper of my batch is expected to be the state topper and his score is 179...There is usually a difference of 20 marks between topper and the cut off ...So even if he gets 182 due to bonuses ...182-20=162..So you can hope to be selected ..All the best!!!!!!
