Hey Aspirant,
If your home state is West Bengal and you had a rank of 834 so it seems that you can get the mechanical engineering branch at the Jadavpur University Kolkata as the last year spot round rank closing was around 840 for the mechanical.
So cross your fingers and hope the trends also continues this year and most probably your counselling will be held in the first phase , so in all you have the chances to get the mechanical engineering branch at JU and hope for the best.
Hope this helps,
Good luck!
