There is no such thing as a cut-off for DMRC Recruitment exam. DMRC only releases the list of shortlisted candidates (not in the order of merit) and later, after few weeks the scorecards and response sheets of the candidates are also made available for the candidates.
Candidates can check the list of shortlisted candidates and their scorecards on the DMRC Career section. To know the marks obtained, the candidates have to enter their "user-id" and "password" which were made available to them after filling the form.
If candidates face any problem then feel free to contact the DMRC help desk number 022-61306222 or can email them at [email protected]
