100% cutoff was announced only by one college ie SRCC that too for science students taking commerce in college
for commerce students cutoff was 97%
Cutoff for commerce in top 10 colleges wary between 92-97% if u choose 3 top courses of B.com (H) , Economic (H) or Physics (H)
U can actually get admission at some bottom ranked colleges with just 66%
If a student cant get that , then he can try out for GuruGobind Singh Indraprastha University or other 2nd tier universities like JNU IndraGandhi open University
However a student will have no future if he gets anything less than 50 %
