B.Sc

A Bachelors (10+2+3) degree (Major/Honours) or equivalent from a recognised University, in any discipline, with a minimum of 50% marks or 5.5 CPI in a 10-point scale (45% marks or 5.0 CPI in a 10-point scale for SC/ST/PD candidates) in major/honours only.

It has excellent scope, you can work as research scientist, technician with pharma, biotech and many more industries.

First you decide if you want to be in management or in technical field.
You can take decision accordingly.
I think, B.Sc is a good option but you have to go for Airline industry later on. So, the chances of getting job will be more.
Also, back offices related courses will add more job opportunities in future. You can consider them also.

Yes, you have a chance to get admission in Agriculture B.Sc in Visva Bharti University in this score. So, apply for it. It is good University.
Best of Luck and Work.

Hi,
Just give the compartment exams and clear it with good marks. If you get good marks in compartment, then you will get admission in any course.
