With a UPCATET rank of 6400 in the OBC category, your chances of getting a BSc Agriculture seat in a government university are very low, as the OBC cutoff usually closes around 5500 rank.

However, you should still:

Register for counselling – sometimes cutoff may extend slightly.

Keep backup options ready like private or semi-government colleges offering BSc Agriculture.

You may get a seat in later rounds or lower-tier colleges, but chances are slim in top government universities.
