What is the best course of action if time is running short during the test?

Choosing to go back to previous questions without leaving any unanswered is a strategic way to maximize your score in a timed testing situation. This approach acknowledges that while you may not have time to answer every question perfectly, ensuring that all questions are answered is crucial. Many tests do not penalize for wrong answers, so it's better to provide an answer, even if it's less than perfect, than to leave any questions blank.

This method also allows you to revisit questions you may have skipped earlier due to uncertainty. You might be able to recall information or make a more educated guess now that you’ve moved through the rest of the test.

In contrast, guessing randomly on all remaining questions would not be efficient, as it does not leverage any partial knowledge you may have. Focusing solely on unanswered questions ignores any previously attempted questions that may still require revision or reassessment. Trying to finish every question with detailed answers can consume too much time, potentially resulting in unanswered questions, which can directly impact your overall score.
