When to Skip a Question (and How to Come Back)

You're two minutes into a reading question on the digital SAT and you still don't know what the author's "primary purpose" is. You've re-read the passage twice. The answer choices all look plausible. Meanwhile, the clock is moving and there are twelve questions left in the module. This is the scenario where most test-takers make their worst decisions — not because they don't know enough, but because they don't have a clear rule for when to walk away.

Why Every Question Carries the Same Weight

No standardized test — SAT, ACT, GRE, GMAT, IELTS, or any other — awards bonus points for solving the hardest question in the section. A question you nail in 30 seconds contributes exactly as much to your score as one you agonize over for four minutes. This sounds obvious, but it doesn't feel that way in the moment. When you've already invested 90 seconds in a problem, the sunk-cost pull is real. Your brain treats abandoning it as a loss, even though moving on is almost always the correct strategic move.

The math is straightforward: if a section gives you 27 questions in 32 minutes, you have roughly 71 seconds per question on average. Spending four minutes on one item means you've borrowed time from five or six others. Those downstream questions might be easier — and on section-adaptive tests like the digital SAT and the current GRE, the difficulty of your second module depends on how well you do overall, so leaving easier questions unanswered is especially costly.

The 90-Second Rule (and What to Do With It)

A workable rule: if you've spent approximately 90 seconds on a question and you're not close to an answer, stop active solving and execute a best-guess-then-mark protocol.

• Make a guess now. On every major standardized test currently in use, there is no penalty for wrong answers. Never leave an item blank. Pick the most defensible option available — even a random guess gives you a floor probability of 25% on a four-option question.
• Flag or mark it. The digital SAT and the Bluebook app have a built-in "Mark for Review" button. The GRE's interface lets you flag questions. Use these features. They exist for this exact purpose.
• Move immediately. Don't hedge. Don't re-read the question one more time. Go to the next item.
• Return with fresh eyes if time allows. After finishing the remaining questions, go back to your flagged items. A question that felt impossible at minute three sometimes resolves quickly at minute twenty, because you've unconsciously processed it and released the pressure.

Roediger and Karpicke's research on retrieval practice shows that stepping away from a problem and returning to it later can improve recall. The same principle applies here in a practical sense: distance from a stuck moment often helps more than brute persistence.

How to Recognize the "Skip" Signal

The 90-second threshold is a guideline, not a law — what makes sense depends on the test, the section, your pacing, and your personal strengths. A quantitative-heavy student might reasonably spend two minutes on a difficult GRE math problem while skipping a vocabulary question in ten seconds. Someone with strong verbal skills might do the opposite. The point isn't to follow a rigid timer but to notice specific cognitive signals:

• You've re-read the question or passage more than twice without new understanding.
• You've eliminated one or two options but can't distinguish between the remaining ones.
• You're guessing between answers based on feel rather than reasoning.
• You're aware that time is running short and you haven't seen the rest of the section.

Any of these signals, especially in combination, means the marginal value of more time on that question is probably lower than the value of that time spent on fresh questions.

What "Stuck" Actually Costs You

On the section-adaptive digital SAT, your performance in Module 1 determines whether you're routed to an easier or harder Module 2 — and the harder module is where the higher scores live. Leaving questions unanswered or rushing the last few because you got stuck early directly affects that routing. The GRE works similarly: your section score is based on total correct answers, so incomplete sections hurt more than difficult ones.

Before your next practice test, set a physical or mental timer for 90 seconds on any question that starts to feel sticky. Practice the flag-and-move action until it's automatic. It's a small habit, and it probably won't transform your score overnight, but it will stop you from trading five answerable questions for one unanswerable one — which is a trade no scoring rubric will ever reward you for making.
