If time remains at the end of the exam, candidates often wonder whether reviewing their answers again is a good idea, or whether it risks second-guessing correct responses that were actually fine the first time around and only feel uncertain in hindsight.
When Review Helps
Reviewing flagged questions you were unsure about, or questions you answered in a rush, can catch genuine errors like a misread question or an accidental wrong selection that would otherwise go uncorrected before submission and cost you points unnecessarily.
When Review Can Hurt
Changing an answer purely out of anxiety, without a specific reason to believe the original answer was wrong, is generally not a productive use of remaining time. Research on this topic generally suggests your first instinct is correct more often than not, so changes should be deliberate, not driven by panic in the final minutes.
A Balanced Approach
A reasonable middle ground is reviewing only the questions you specifically flagged during the exam, rather than rereading every single question from the beginning, which conserves time while still catching the answers most likely to actually need a second look before you finalize your submission.
Putting This Into Practice
Exam strategy is ultimately personal, so feel free to adapt this recommendation to whatever genuinely helps you feel calmer and more focused, since that comfort is what actually translates into better performance on test day.
A Final Thought
As your exam date approaches, narrowing down to a short, personalized list of the strategies that have worked best for you during practice testing keeps your final preparation focused rather than scattered across too many ideas at once. If possible, try this exact approach during a full practice exam under real time pressure at least once, since some strategies feel noticeably different once genuine time constraints and uncertainty are involved.
Focused review of flagged or rushed questions is worthwhile, but wholesale second-guessing of confident answers is usually not the best use of your remaining time.
