Hello Divyanshu,

In order to get admission to either of the courses under B.Sc Physical Sciences you need to have passed your 10+2 examination with physics, chemistry and mathematics with a minimum percentile of 50% marks which in case of an SC/ST would be reduced to 45% marks. It has a merit based admission which is based on the qualifying examination. The course is applicable for 3 years and has a fee of 80,000 rupees. 

I hope this helped.

All the best!!
