Humans do not learn best through single exposure. To retain information over time, we need repeated and intentional engagement with it. This is especially true for GMAT preparation. If you want to build long-term mastery, you must consistently review and revisit material you have already studied.
Let’s say you start your prep by studying number properties. You read the lesson, take notes, and work through a few practice problems. That is a good start. But if you move on and do not return to number properties for several weeks, you will likely forget a large portion of what you learned. On the other hand, if you revisit the topic periodically, you will reinforce your understanding and improve your ability to apply the material under pressure.
To make the most of your review, here are a few action items you can follow:
1. Set a review schedule.For each topic you study, plan at least three review sessions over the following two weeks. For example, if you study exponents on Monday, schedule quick review sessions on Thursday, the following Monday, and again the following Friday. The intervals do not need to be exact, but they should be spaced to help your brain recognize the material as important.
2. Use active recall.Passive review, such as rereading notes, is less effective than actively trying to remember and apply what you have learned. Quiz yourself with flashcards, try to solve old problems without notes, or explain concepts out loud as if teaching someone else. The goal is to challenge your memory and force your brain to work.
3. Mix review into your regular study sessions.Do not reserve separate time blocks only for review. Instead, incorporate 15 to 20 minutes of review into each study session. For instance, if you are studying geometry today, start by reviewing a few questions from algebra or number properties. This approach helps keep earlier material fresh and reduces the chance of forgetting key topics.
4. Track your retention.As you review past topics, note where you still feel confident and where you are struggling. If you consistently miss certain types of questions, that is a signal to revisit that sub-topic in more depth. Maintaining an
error log or review journal can help you spot these trends early and address them before they become larger problems.
5. Revisit full practice sets.After you have reviewed individual topics, complete mixed-topic quizzes or timed sets to test your ability to apply what you have learned in varied contexts. This kind of integrated review will improve both retention and test-day readiness.
The bottom line is this: your brain prioritizes what it sees as important. If you study a topic once and never return to it, your brain treats it as low priority. But if you reengage with the topic regularly, you are signaling that the material matters, and your brain responds by reinforcing those memory pathways.
Consistent and structured review is one of the most effective tools for preventing knowledge gaps and building reliable test-day skills. Make it a regular part of your prep and your GMAT performance will improve.
