Dear Aspirant 

First of all Congratulating you on your nice performance and I would like to tell you that based on your rank in general category and considering the fact that you belong to Obc category it is very difficult for you to get core branches but still you may get civil engineering or chemical engineering and for that you need to wait till spot or special round counselling conducted at the end. I would also tell you that don't fully depend here, keep a backup ready. 

Good luck for your future :) 

Feel free to ask if you have any further queries.
