How GRE navigation works
ETS lets you move forward, go back, and change answers within the current section using Mark and Review. Difficulty adapts between the two sections of each reasoning measure. Do not carry over navigation rules you remember from another exam.
Verbal has 12 questions in 18 minutes, followed by 15 questions in 23 minutes; Quant has 12 questions in 21 minutes, followed by 15 questions in 26 minutes. Each time limit applies to its own section: you cannot return to an earlier section. Analytical Writing comes first and allows 30 minutes for one Analyze an Issue task.
How difficult a question feels is not a measure of your performance. During the test, focus on the information and the question being asked rather than trying to decode the adaptive design.
Recognize productive and unproductive impasses
It may make sense to continue if you are making progress: you have isolated an equation, found a supporting sentence, or eliminated an ambiguity. Rereading the same line without making progress is a different signal. In practice, set a limit based on progress rather than using the same number of seconds for every question.
Before moving on, leave yourself a simple mental note: “two options remain; find the concession” or “got a result; check the units.” Your return will be more useful than starting over. Mark questions selectively; if everything is marked, the list can no longer help you prioritize.
Annotated example from the first Quant section
The first Quant section currently has 12 questions in 21 minutes. The table below is a fictional teaching example, not a schedule prescribed by ETS. The times shown are the time remaining.
| Stage | Observation | Decision and rationale |
|---|---|---|
| 18 minutes remaining | Two questions completed; the third still needs a clear mathematical model | Choose a tentative answer if possible, mark it, and move on |
| 14 minutes remaining | Questions 4–6 completed; Question 5 has a questionable unit | Mark Question 5 for a focused check without repeating every calculation |
| 9 minutes remaining | Every question has had a first pass | Find unanswered questions, then return to those with the clearest next step |
| 6 minutes remaining | Still stuck on Question 3 after another attempt | Stop this attempt and work on a more promising check |
| 2 minutes remaining | One answer is missing, and two choices remain uncertain | Fill in the missing answer, then review risky question interpretations and entries |
Choose what deserves a second look
When you return, distinguish three cases. Fix an identified error: you missed a condition, reversed a ratio, or chose a word that conflicts with the context. An unfinished question with a clear approach may be worth completing. Vague concern about a well-supported answer does not necessarily call for a change.
Changing an answer is neither inherently good nor bad. Ask what new information supports the change. “It seems too easy” is not evidence. On the other hand, keeping an answer out of fear of changing it would be a mistake if you have just noticed a decisive condition.
The pitfall
The pitfall to avoid
Spending several minutes trying to solve a question because you have already invested so much time in it. Time already spent cannot be recovered. Compare what you can still gain by returning to it with what remains to be done.
Check answers according to question type
ETS does not deduct points for incorrect answers in the reasoning measures and recommends answering every question. Keep this rule separate from how much time you spend working out an answer: filling every response field does not require fully solving every problem.
Your final check depends on the question type. For Numeric Entry, check units and rounding. For Text Completion, reread all the blanks together. For Sentence Equivalence, check both completed sentences. In reading questions, compare the scope of your answer with the passage. These focused checks are more useful than rereading everything indiscriminately.
Evaluate your decisions on a short set
After a section, note one question you moved past too late, one useful return, and one poorly justified answer change. Revisit those decisions by explaining what signal you had at the time, without blaming yourself for not knowing the explanation in advance.
Use your next session to test one change, such as limiting returns when you have no new approach. Then compare the number of questions you actually addressed and the quality of your reasoning. These observations can guide your approach; they cannot decode the adaptive algorithm or calculate an official score.
Key takeaways
- Navigation is limited to the current section.
- Return to a question when you have a specific approach or check.
- Answer every question without spending all your time on one impasse.
