Hi Pallavi,

You want to know the criteria for admission to B.Sc. Non-Medical but as you know every college as well as every university has its own criteria so you need to be more clear with which university or college you want to get admission into

Generally for most of the colleges as well as universities the criteria is that the candidate should have passed 10+2 th with 50% aggregate and 45% for reserved categories.  

Hope it helps :)
