Rahul if you are able to cross the total ST category JEE Advanced exam cut-off and individual subject cut-off in all the 3 subjects including chemistry then your rank will be declared on 10th June 2018. According to last year cut-offs, you will pass out the cut-offs and it is expected that this year cut-off will fall down a little more so most probably you will clear the cut-off. And in the worst case if you are not able to clear the cut-off then also your result will be declared, you will be able to see your scorecard but you will not be allotted any rank.

Feel free to ask if you have any more queries. All the best!!
