Hello Aspirant, 

Talking about the previous trends for admission in phd physics, the general cutoff was about 118 in CU of Gulbarga.

As you are a reserved candidate and want to do phd in physics then the cutoff for sc candidates was 72 for CU Srinagar.

Considering your chances for admission in a CU, it is predicted that you are on a thin line and basically on the verge but still have chances for admission.

Wishing you all the very best..
