Hello there!
Greetings!

Sorry to tell you dear but you haven't mentioned your category, so I am considering you from general Category , with 73 % in pcb a student from general Category cannot get admission in DU as cut off DU is quite high,

DU is a renowned university and is very famous for its high cut off.
If I tell about this year i.e 2019 , then even in 8th cut off list of DU ,at least 84 % was required to get admission in bsc life sciences.
So, unluckily with only 73% aggregate marks in Physics, Chemistry and Biology you cannot get into DU.

You can check DU cut off marks yourself as well by going through its official website for which link is provided below :-
