Hello Gagan

It totally depends on the cutoff wethere you can get admission in DU or not, but if you want to get into DU under the Sikh Minority qouta then you will need to get the Sikh Minority Certificate issued to you by the DSGMC- Rakab Ganj Gurudwara, New Delhi.

 Out of the 4 Khalsa schools namingly, 

SGTB Khalsa College 

SGND Khalsa College 

SGGSCC Khalsa College 

Mata Sundri College 

A seperatemerit will be given name as 'Sikh Minority Quota' under which the cutoffs will be very low when contrastedwith the unreserved category

cutoffs  for BA(H) Punjabi, Hindi and History goes very low for like 45%-80% even in the third list. 

Cut offs goes even lower  for science  for courses like Bsc(H) Electronics, Chemistry . 

cutoff for Bcom, Bcom(H) and BA(H) Economics are still high in the minority records moreover. They go like 85–87% for minimum depending upon their college.

I would recommend you to go with a back-up plan - sit for DU entrance test.

GOOD LUCK FOR YOUR FUTURE 

THANK YOU
