Which button is used to finalize and submit the exam?

To finalize and submit the exam, the "Submit Exam" button is specifically designed for that purpose. This button indicates that the participant is ready to conclude the examination process and submit their responses for evaluation. It is crucial because it signifies that all questions have been answered or that the participant is satisfied with their current selections, ultimately triggering the system to collect the data for scoring.

Other options serve different functions within the exam interface. For instance, the "Next" button typically allows the test-taker to proceed through the questions without actually submitting the exam. The "Marked for review" button enables users to highlight questions they might want to revisit later, but it does not submit any of their answers. The "Review All" button is likely intended for accessing a summary of the attempted questions and evaluating them before final submission, rather than finalizing the exam itself. Thus, the "Submit Exam" button clearly stands out as the necessary action for completing the examination process.
