Regular program with a 49% score is difficult if you belong from general category because minimum eligibility criteria for most universities is 50% in a B.Com degree.even cuet requires the same percentage.

But still you can pursue M.Com even after a long gap since completing your B.Com in 2015 many universities offer admission to older students and have no upper age limit for postgraduate courses.you can go for online or distance courses offered by IGNOU .

Happy to help you..
