How to Use the Flag-for-Review Feature on the Digital SAT

The SAT flag for review feature is one of the most useful tools built into the digital SAT testing application, and most students either ignore it entirely or use it so much that it becomes meaningless. The flag lets you mark a question during a module so you can come back to it before time runs out. Used well, it protects your pacing, reduces anxiety on hard questions, and gives you a systematic way to review your work. Used poorly, it becomes a source of stress and wasted time.

Here's how to build a flagging strategy that actually helps your score.

What the flag-for-review feature does

On the digital SAT, each question has a small flag icon you can click to mark it. Flagged questions appear highlighted in the question navigation panel at the bottom of the screen, making them easy to find when you want to return to them. You can flag and unflag questions at any time during the module.

The flag doesn't change your answer or affect your score in any way. It's purely an organizational tool. If you flag a question and never return to it, whatever answer you selected (or left blank) still counts. The flag is just a bookmark for yourself.

This is important to understand because some students treat the flag like a pause button, as if flagging a question somehow puts it on hold. It doesn't. You should always select your best answer before moving on, even if you plan to come back.

The two-pass approach

The most effective way to use the flag feature is as part of a deliberate two-pass strategy. This approach divides each module into two phases.

Pass 1: Answer everything, flag the hard ones

Go through every question in order. For each question, do one of three things:

1. Answer confidently and move on. If you know the answer or can solve it quickly, select it and don't flag. Most questions should fall into this category.

2. Make your best guess and flag it. If the question is hard, confusing, or requires more time than you want to spend right now, select the answer that seems most likely and flag the question. Don't leave it blank. Don't spend five minutes agonizing. Make a reasonable choice and move forward.

3. Eliminate what you can, guess from what's left, and flag it. If you're genuinely stuck, eliminate any answer choices that are clearly wrong, pick from the remaining options, and flag it. Even a guess between two choices gives you a 50% chance, which is better than running out of time on later questions.

The goal of Pass 1 is to see every question in the module and give every question an answer. This ensures you never lose points simply because you ran out of time.

Pass 2: Return to flagged questions

Once you've gone through every question, use the navigation panel to jump back to your flagged questions. Now you can spend your remaining time on the questions that need more thought. You might:

• Reread the passage more carefully
• Try a different approach to a math problem
• Reconsider answer choices you previously eliminated
• Double-check your work on questions where you weren't confident

The two-pass approach works because it separates speed from accuracy. In Pass 1, you prioritize coverage. In Pass 2, you prioritize depth. This prevents the common problem of spending too long on question 5 and then rushing through questions 25 through 27.

Our time management guide covers pacing strategies in more detail, and the flag feature is a key part of executing those strategies effectively.

How many questions should you flag?

This is where most students need calibration. Flagging too many questions is almost as bad as not flagging at all.

The sweet spot is 3 to 7 flagged questions per module.

Here's why. Each Reading and Writing module has 27 questions in 32 minutes. Each Math module has 22 questions in 35 minutes. If you flag 10 or more questions, you won't have enough time in Pass 2 to meaningfully revisit all of them. You'll end up scanning your flagged questions, feeling overwhelmed, and either changing answers randomly or giving up on the review entirely.

On the other hand, if you never flag anything, you're either spending too long on hard questions during Pass 1 (which hurts your pacing) or you're so confident in every answer that you don't need a review strategy (which is rare, even for top scorers).

Calibrate during practice. When you take practice tests on MockCamp or other platforms, pay attention to how many questions you flag and how much time you have left for Pass 2. Adjust your flagging threshold until you consistently have 2 to 5 minutes remaining after Pass 1 to review your flagged questions.

When to flag a question

Not every hard question deserves a flag. Flag strategically based on these criteria:

Flag when you're between two answer choices

If you've eliminated two options and you're stuck between the remaining two, flag it. Coming back with fresh eyes after seeing other questions often helps you spot a distinction you missed the first time. This is especially common on reading questions where two answer choices seem very similar.

Flag when the question requires a long calculation

Some math questions are straightforward but time-consuming. If you know how to solve it but the calculation will take two or three minutes, select your best estimate, flag it, and come back if time allows. Don't let one lengthy computation eat into time you need for other questions.

Flag when you misread or need to reread

Sometimes you realize partway through a question that you misread the passage or misunderstood what was being asked. Rather than restarting from scratch in the moment, flag it and move on. When you return in Pass 2, you'll be able to read more carefully without the pressure of an untouched question bank ahead of you.

Flag when your answer feels uncertain

Trust your instincts here. If you selected an answer but something feels off, that's worth a flag. In Pass 2, you can examine whether your uncertainty is justified or just test anxiety talking.

When NOT to flag a question

Don't flag questions you're confident about "just in case"

Some students flag 15 questions per module because they want to double-check everything. This defeats the purpose of the flag. If you're confident in your answer, move on. Save your flags for questions where additional review could actually change your answer.

Don't flag questions you have no idea about

If you've read the question twice, eliminated what you can, and made your best guess, but you genuinely don't know the content being tested, flagging it probably won't help. Coming back to a question you don't understand won't magically give you the knowledge to answer it. Use your Pass 2 time on questions where a second look could make a difference.

Don't flag as a substitute for answering

The flag is not a "skip" button. Every flagged question should have an answer selected before you move on. If you flag a question without answering it, you risk running out of time in Pass 2 and leaving it blank. Always answer first, then flag.

Common mistakes with the flag feature

Mistake 1: Changing too many answers in Pass 2

Research on test-taking consistently shows that your first instinct is usually correct. When you return to flagged questions, don't change your answer unless you have a specific reason to. "This other option looks better now" isn't a specific reason. "I realize I misread the question and it's asking about X, not Y" is a specific reason.

If you find yourself changing more than one or two answers per module during Pass 2, you're probably second-guessing yourself rather than genuinely finding errors.

Mistake 2: Not practicing with the flag feature

Many students encounter the flag feature for the first time on test day and don't know how to use it efficiently. Practice using it during every practice test. Get comfortable with the mechanics: where the flag icon is, how to navigate to flagged questions, how to unflag after reviewing. These should be automatic on test day so you can focus on the content, not the interface.

Try a free practice test on MockCamp and specifically practice your flagging strategy. Count how many questions you flag per module and track whether your flagging patterns are helping or hurting your score.

Mistake 3: Spending too long on Pass 1

The two-pass approach only works if you actually leave time for Pass 2. If you spend 30 out of 32 minutes on your first pass through a Reading and Writing module, you only have 2 minutes for review, which might be enough for one or two questions at most. Aim to finish Pass 1 with at least 3 to 5 minutes remaining.

This means holding yourself to a per-question time limit during Pass 1. For Reading and Writing, that's roughly 60 to 70 seconds per question. For Math, it's roughly 80 to 90 seconds per question. If you hit the limit and aren't close to an answer, select your best guess, flag it, and move on.

Mistake 4: Ignoring the navigation panel

The question navigation panel at the bottom of the screen shows all questions in the module, with flagged ones highlighted. Some students forget it's there and try to scroll back through the entire module to find their flagged questions. Learn to use the navigation panel to jump directly to flagged questions. It saves significant time.

The flag feature and the adaptive format

On the adaptive digital SAT, your performance on Module 1 determines whether you get an easier or harder Module 2. The flag feature works the same way in both modules, but your flagging strategy might shift slightly.

In Module 1, every question contributes to the routing decision. Getting easy and medium questions right is essential for being routed to the harder module (which you need for the highest scores). This means you should be especially careful about not spending too much time on any single Module 1 question. Use the flag aggressively in Module 1 to maintain your pace.

In the harder Module 2, the questions are designed to be more challenging, with more tempting wrong answers and more complex reasoning. You'll likely flag more questions in Module 2 than in Module 1, and that's expected. The key is keeping your flags to a manageable number so you can meaningfully review them.

Building your personal flagging strategy

Your flagging strategy should be tailored to your strengths and weaknesses. Here's how to develop one.

Step 1: Take a practice test without any flagging rules

Just take the test naturally and notice your instincts. Did you get stuck on certain questions? How long did you spend on the hardest questions? Did you rush at the end?

Step 2: Take a practice test with the two-pass approach

Enforce the two-pass strategy: answer every question, flag the hard ones, come back in Pass 2. Note how many questions you flagged and how much time you had for review.

Step 3: Compare your results

Did the two-pass approach improve your score? Did you manage your time better? Did you have fewer questions left unanswered? For most students, the two-pass approach leads to a small but meaningful improvement, typically 20 to 40 points, primarily from better time management and fewer unanswered questions.

Step 4: Refine your threshold

Based on your practice, set a personal flagging limit. If you consistently flag 10+ questions and can't review them all, raise your threshold for what's worth flagging. If you flag only 1 or 2, consider whether you're spending too long on hard questions during Pass 1.

Our practice test guide covers how to review your practice tests to identify patterns like these.

The bottom line

The SAT flag for review feature is a simple tool with a big impact when used strategically. Build your approach around the two-pass method: answer every question in Pass 1, flagging 3 to 7 questions that deserve a second look, then use your remaining time in Pass 2 to revisit those flagged questions with fresh eyes and focused attention. Always answer before flagging, don't change answers without a specific reason, and practice your flagging strategy during every practice test so it's automatic on test day.

The students who use the flag feature most effectively aren't the ones who flag the most questions. They're the ones who flag the right questions and have enough time to actually benefit from the review.

Frequently Asked Questions

Does flagging a question affect my score?

No. The flag is purely an organizational tool for your own use during the test. It doesn't change how the question is scored, and the testing system doesn't track which questions you flagged. Whether you flag zero questions or every question, your score is determined only by the answers you select. The flag is just a visual bookmark to help you find questions you want to revisit.

Can I change my answer when I return to a flagged question?

Yes. You can change your answer on any question at any time during the module, whether it's flagged or not. The flag just makes the question easier to find in the navigation panel. However, be cautious about changing answers. Only change your answer if you have a clear, specific reason, such as realizing you misread the question or made a calculation error. Changing answers based on a vague feeling that another option "looks better" more often hurts than helps.

What if I run out of time and still have flagged questions?

If time runs out before you get to all your flagged questions, whatever answer you selected during Pass 1 still counts. This is exactly why you should always select an answer before flagging. Your Pass 1 answer is your safety net. The flag gives you the option to improve that answer if time allows, but it guarantees you won't leave the question blank even if you never return to it.

Should I use a different flagging strategy for math versus reading?

The core approach is the same for both sections, but the reasons you flag might differ. In math, you'll typically flag questions that require long calculations or where you're not sure which method to use. In reading and writing, you'll typically flag questions where you're torn between two answer choices or where you need to reread the passage more carefully. The target number of flags (3 to 7 per module) applies to both sections, though you may find you naturally flag slightly more in whichever section is harder for you.
