B.Sc

You need to have minimum 50% marks for admission in B.Sc Physics.

Every college has different criterion, so kindly check the same with the college itself. Usually, it is the date of birth.

Yes, you surely can apply for a job in defense services once you complete B.Sc Mathematics.

For B.Sc in computer Science, the cut off was 71.39%.

It is not only about Biology, tell me the total percentage you have scored, so that I can guide you better.

Hi,
Selection is based on UPCATET. The candidate must have passed intermediate in Agri. Science/PCB/PCM/PCMB. Final admission of the students will be done based on the cut-off percentage of marks. For General & OBC category candidates, the cut-off percentage marks in UPCATET is 20% whereas for SC & ST candidates, the minimum required aggregate is 10%.
Regards.

B.Sc. Agri doesn't require NEET score. You should go for a good college.
All the best.
