Dear aspirant

Every year the number of participating Candidates in JEE vary a lot so on the basis of ranks it is hard to look for the chances of getting into any Institute. But ya as you belong yo SC category you need around 100+ to get into your dream Institute. But for the branch os CS you must score 150+ so that there are fair chances to get  into NIT Trichy. 

I hope this helps you. Good luck!!
