Hello, hope you are doing well!

Delhi University School of Open Learning(SOL) offers Masters of Commerce only if one fulfills the basic eligibility criteria (general category) i.e.-

50% of seats are filled through merit based selection and rest 50% seats are filled on the basis of results of entrance test conducted by the university.

Direct admission or Merit based selection: Minimum 65% aggregate in BCom (Hons) or minimum 75% aggregate in BCom (Pass).

Selection through entrance test: Minimum 50% aggregate in BCom (Hons) or minimum 55% aggregate in BCom (Pass).

For regular colleges also, the eligibility criteria is quite similar. 65% in DU is just the basic criteria for you to get admission into MCom. But it totally depends on the other students' percentages now and the number of seats. You are at the very margin of the eligibility criteria so there is no majority percentage that you will definitely be selected on merit based method. But you can try for the entrance exam to be on the safer side that even if you don't get selected in the merit based criteria you can definitely be selected on the basis of entrance.

All the best!
