Hello Santosh, 

There are many colleges under Delhi University that provide B.sc. Physical Science as a subject course. Have you registered yourself in the Delhi University online portal? If you haven't then you should as soon as possible since it's been a few weeks since the application processes have already started. 

If you belong to the ST category then with 78% you can land up in almost any college under DU, even in the north-campus as well! If you belong to the General category then your chances are less in the colleges of the north campus but you can still get into the south-campus colleges. Just make a list of all the south campus colleges of DU (the list is also available on Google) and start applying to them Asap! Good luck!

greetings aspirant,

if you are an unreserved category student, you may not get admission in delhi university as 78% is not at all enough for du.

however is are a reserved category student, you will get admission in many good colleges of delhi university.

pls refer to the link below to get insights of last years cut-offs:

If you are an unreserved student drop the idea of delhi university because it is next to impossible,instead  you may get admission in amity university, noida or jamia milia islamia, IPU if you have appeared for their respective entrance.
