Dear Aspirant,
It depends upon the college in which you want admission. Some colleges gives admission solely on the marks in 12th like Delhi University, while some just set a minimum required marks, and then separately conduct an entrance test for their college like IITs/NITs etc. There are some colleges like medical colleges which gives admission on the basis of NEET rank and to be eligible for NEET exam one only needs 50% marks in PCB.
Hope this helps. Thank you.
