What should candidates do if they encounter a question they do not understand?

Making an educated guess and moving on is a strategic approach to managing time effectively during an exam. When candidates encounter a question they do not understand, making an educated guess enables them to make use of their existing knowledge and reasoning skills to potentially answer the question correctly, even if it's uncertain. This approach minimizes the risk of losing valuable time during the exam, which can lead to not completing the test or missing out on easier questions ahead.

In a timed situation, it's crucial to maintain a steady pace. By guessing and moving forward, candidates preserve time for questions they may feel more confident answering. Moreover, unanswered questions do not contribute to a candidate's score, so it is generally advisable to at least attempt every question.
