What should a candidate do if they encounter a difficult question on the exam?

When faced with a particularly challenging question on an exam, moving on and returning to it later if time permits is a practical and effective approach. This strategy allows the candidate to manage their time more effectively. By not becoming overly fixated on a single difficult question, the candidate can continue to answer other questions that may be easier or more straightforward, potentially accumulating more points.

Additionally, once the candidate has gone through the easier questions, they may find that a different perspective or additional insights from the surrounding questions help jog their memory or clarify their thoughts on the difficult question upon returning to it. This method balances the need to address all questions in the exam while allowing for the possibility of revisiting tougher ones with a clearer mind later on.
