Hello

Eligibility criteria  for bsc agriculture are:

You should have eligible marks for admission in state entrance exam

Candidate should score minimum 50% marks in 12th

Since every year cutoff varies from college to college and it depends upon many thing such as number if student givem exam , highest marks , difficulty level of exam..

70 percentile is good you can expect good colleges. So you can go for it.

Feel free to ask

Good Luck...
