How to review an SAT practice test: the error log method

Your practice test score tells you where you are. The review is where you find the points. A good review takes about as long as the test itself, roughly two to three hours, and ends with a short list of what to practice before your next test. The method below sorts every miss into one of four causes (content gap, misread, careless, or time), logs it, and gives each cause its own fix.

Before you start

Mark your guesses during the test. Each time you guess, write the module and question number on your scratch paper. A lucky guess is a miss you happened to get away with, and it belongs in your review.

Review within two days. You need to remember why you picked each answer, and that memory fades fast.

Find the review screen. For a Bluebook practice test, go to My Practice and open Score Details. College Board's Bluebook page explains that it lists every question, your answer, and the correct answer, with a Review button that opens the question and its explanation.

Step 1: rework each miss before you read the explanation

Go through every wrong answer and every marked guess. Cover the explanation and solve the question again on paper with no timer.

This one step does most of the sorting for you. If you get it right now, the problem wasn't what you knew. It was how you read it, a slip, or the clock. If you still get it wrong, or you can't figure out how to start, you have a content gap.

Only after your second attempt should you read the explanation. Then write one sentence in your own words on why the right answer is right.

Step 2: put each miss in one category

Use the first thing that went wrong. Each miss gets one category.

Content gap. You didn't know the rule, formula, or method. For example, you didn't know that a semicolon needs a complete sentence on both sides, or you didn't know how to find a circle's radius from its equation.

Misread. You knew how to do it but answered a different question. You solved for $x$ when the question asked for $2x$, or you picked the main idea of the passage when the question asked about the purpose of one sentence.

Careless. You understood the question and the method but slipped while carrying it out. Common examples are a dropped negative sign, an arithmetic error, a number copied wrong, or clicking a different choice from the one you meant.

Time. You ran out of time, rushed, or guessed because the clock was short. This includes questions you would have gotten right with one more minute.

Step 3: log it

Keep one running error log for all your practice tests, in a spreadsheet or a notebook. Here's what a few rows look like:

Add a "Redo" column on the right. You'll fill it in during Step 6.

Step 4: fix each category differently

Content gaps: learn it, then drill it. Read a short explanation of the skill, such as the SAT Owl guide to Boundaries questions or circle questions. Then do 10 to 15 questions on that one skill. College Board's Student Question Bank lets you filter official questions by section, domain, skill, and difficulty, which makes this easy. Content gaps take the longest to fix, so start them first.

Misreads: build a checking habit. Look for the trigger. Did you answer for the wrong variable, mix up units like minutes and hours, or answer a different question about the passage? Then add one habit that targets it. In Math, write what the question asks for at the top of your scratch work. In Reading and Writing, reread the question's last sentence before you pick an answer and ask whether your choice answers that exact question.

Careless errors: find your pattern. Careless errors tend to repeat. Track yours across two or three tests and you'll usually see the same few slips, such as distributing negatives, copying numbers from the screen, or entering answers. Once you know yours, add a quick check aimed at it: plug your answer back into the original equation, graph both sides in Desmos, or reread the number you typed before moving on.

Time: find where the minutes went. The average pace is about 71 seconds per Reading and Writing question (32 minutes for 27) and about 95 seconds per Math question (35 minutes for 22). Look for the one or two questions that ate four minutes each. The fix is usually a rule, not speed: flag any question that passes two minutes, move on, and come back at the end. Then practice with timed modules. Do 27 Reading and Writing questions in 32 minutes, or 22 Math questions in 35 minutes.

Step 5: count the categories and set your plan

Tally each category. Here's one example: 14 misses, with 7 content gaps, 3 misreads, 2 careless errors, and 2 time problems. This student should spend most of the next two weeks on the skills behind those 7 content gaps, and use one easy habit to cut down the misreads.

If misreads and careless errors add up to more than your content gaps, you have the cheapest points on the test waiting for you. Those come from habits, not new material, and can improve within a week.

Also compare Module 1 with Module 2. College Board explains that the second module of each section is slightly harder or slightly easier depending on how you did on the first. Misses in Module 1 can cost you twice: once for the question, and again if they push you into the easier second module. If your Module 1 log is full of misreads and careless errors, slow down a little in Module 1.

Step 6: redo the questions later

After one to two weeks, rework every question in your log without looking at your notes. Mark the Redo column right or wrong. A question you get wrong again is still a gap, so it goes back on your practice list. Do this before your next full practice test so you don't carry the same mistakes forward.

Review mistakes to avoid

• Reading explanations without reworking the question first. It feels productive, but less of it sticks.
• Skipping lucky guesses. They show up as correct on your score report but are really gaps.
• Spending all your time on the hardest questions. A missed easy question is the cheapest point to get back.
• Taking the next test before acting on the log. A new score won't change if your practice hasn't.

Try it on your next test

The method works with any full-length test. SAT Owl's free full-length adaptive practice test shows which second module you reached in each section and your accuracy in all eight content areas, weakest first, which speeds up Step 5. Every miss comes with an explanation you can read after reworking the question yourself.
