Hi subhajit saha ,

Considering your rank you there is a fair chance that you can get into some top seat in some good colleges but chance sfor jadavpur is quite low for that you may have to wait till last round.. So don't missout the registration process. Do participate in the counselling. I hope this helps. 

All the best 

 hope it will help you. FOR MORE QUERY COMMENT BELOW AND UPVOTE :)
