Answers are given on an answer sheet (OMR) and not in the test booklet. Tests of reading and listening are marked by an OMR device and for that reason need to be properly filled in. Candidates are required to use a pen while completing the OMR form.
In case an OMR form is not properly filled in (e.g. incorrect or missing candidate number) and the OMR device cannot read it, Global Hippo Association keeps the right to disqualify the candidate if the identity of the candidate cannot be established.
