What is the best approach to guessing on a difficult question?

• A. Skip the question entirely.
• B. Choose randomly without elimination.
• C. Eliminate clearly wrong choices when possible and make an educated guess.
• D. Select the longest option.

Answer: (D)

When guessing on a difficult question, the strongest move is to narrow the field first. Look for obviously wrong options and cross them out based on what you know from the material or the question stem. That leaves you with a smaller set to consider, which improves your odds compared to a blind guess.

If you can trim the choices down to two or three, your chance of getting it right is much better than random guessing. The key is to avoid relying on superficial cues like how long an answer is. Length isn’t a reliable indicator of correctness—long distractors are common and can mislead even when they contain extra, irrelevant details.

On many civil service exams, you’re not penalized for guessing, so it’s better to answer every question. If you truly can’t eliminate anything, pick one of the remaining options and move on, returning later if time allows. The main idea is to use elimination to improve your odds rather than choosing based on guesswork or length.
