What should one do if they feel uncertain about their answer?

When faced with uncertainty about an answer, reviewing the passage again before making a decision is a beneficial strategy. This approach allows the test-taker to revisit the material and find key details or context that may illuminate the correct answer. Taking the time to re-examine the passage can lead to a deeper understanding of the question and the potential answers, helping to eliminate confusion and increase confidence.

By contrast, changing the answer immediately without further thought can lead to errors if the initial instinct was correct. Leaving the question blank forfeits the opportunity to potentially earn points if the correct information is found upon review. Similarly, choosing the first option available can lead to an arbitrary answer that may not reflect the test-taker's best judgment or knowledge on the subject. Thus, carefully re-evaluating the passage often proves to be the most thoughtful and effective response when uncertainty arises.
