@Suyash_Srivastava My apologies, overlooked the normalized marks. By past year's data, it seems that your AIR could be around 25k, but as this year's scores are lower, you could get a higher rank than (maybe between 15-20k).
@Vishnu I know I might be stating the apparent, but your JEE score is much lower than what is expected from seeing your class 12 result. It is difficult to predict the rank in such a case, because data extrapolation in such a case would be difficult. As a very rough guess, I can say rank could be around 20000 considering your very high board results.
@ajmal_mohamed There is not much data for TN Board marks vs rank / position. I cannot say fir sure, but rank could be beyond 26,000.
@Kavya_Barnadhya_Haza Pls wait till the declaration of JEE Main All India Rank to determine chances of NITs admissions.
