How can candidates identify unanswered questions during the examination?

During an examination, candidates can identify unanswered questions by utilizing the features provided by the examination interface. When a candidate clicks on the hand icon or presses the NEXT key, the system often highlights which questions have not been answered, allowing candidates to easily navigate back to those questions. This function acts as an immediate visual cue, helping candidates manage their time efficiently and ensure they attempt every question before submitting their exam.

The other options, while they may seem reasonable, do not effectively address the examination process as it is typically designed. The question summary page is more for an overall view but may not directly indicate unanswered questions in all interfaces. Marking with a special highlighter is not a feature commonly found in digital exams. Similarly, a physical checklist would not be applicable in a digital context where the examination is conducted online. Therefore, the function of clicking on the hand icon or pressing the NEXT key is the best method to ensure all questions are addressed.
