Dear Raksha ,

As you have not told about any Entrance exam that you have appeared , so I am giving the basic eligibility criteria that is required to get admission in B.Sc Agriculture courses :

You should have scored minimum 55% marks in your 10+2 qualifying exam . So you are requested to calculate your 12th board score percentage according to your marks ! The higher percentage you obtain , the higher merit rank you can gain .

Well, you can refer to this link  for more details about Agricultural sciences:

Hope this helps !

Best wishes !!
