For paper-based examinations, the test answers are marked by an OMR device and for that reason need to be properly filled in. Candidates are required to use an HB pencil or a blue/black ball point pen while completing the OMR form.

In case an OMR form is not properly filled in (e.g., incorrect or missing roll number) or scanned and the OMR device cannot read it, ISO keeps the right to disqualify the candidate if the identity of the candidate cannot be established.

For online examinations, in case of suspected malpractice, ISO keeps the right to re-test the candidates using a parallel test and under the invigilation of the ISO staff.

The first-round perfect scorer will appear in the Final round of competition.
