What must examinees do before the established time limit expires?

The requirement for examinees to submit their answer sheet before the established time limit expires is crucial in ensuring that all answers are considered valid and accounted for. By submitting the answer sheet, examinees formally indicate that they have completed the exam and are ready for their materials to be evaluated. The response must be made within the time limit, allowing for a structured and fair assessment process where all participants adhere to the same guidelines.

Reviewing answers is generally encouraged; however, this action must occur before submission. Contacting the proctor may be necessary in certain circumstances, but it does not fulfill the primary requirement of submitting answers. Leaving the examination room before the end of the allotted time would also not satisfy the obligation to complete the examination and submit results properly, so focusing on the submission of the answer sheet is essential for maintaining the integrity and order of the examination process.
