Preparing for the SAT can feel like navigating a maze. Even the most prepared students make avoidable mistakes that cost them valuable points. Understanding these common SAT mistakes before test day can be the difference between a good score and a great one. Let's walk through the ten most frequent errors students make and, more importantly, how you can avoid them.
1. Not Reading Questions Carefully
This is the most common mistake, and it's completely preventable. Students rush through questions and miss key words like "except," "not," or "least." In the Reading and Writing section, you might miss that a question asks what the passage "suggests" rather than "states directly." In Math, you might solve for x when the question asks for 2x.
How to avoid it: Underline or circle key words in every question. Train yourself to pause for two seconds before answering to confirm what's actually being asked. During SAT practice tests, track how many questions you miss simply from misreading—you'll be surprised.
2. Spending Too Much Time on Hard Questions
Getting stuck on one difficult question can derail your entire test timing. Some students spend five minutes on a single problem, leaving easier questions unanswered at the end. Remember, every question is worth the same number of points, whether it's easy or hard.
How to avoid it: Use the two-minute rule. If you haven't made significant progress on a question after two minutes, mark it and move on. Answer all the questions you know first, then return to the challenging ones with whatever time remains. This SAT time management strategy ensures you capture all the points you can.
3. Leaving Questions Blank on your SAT Test
There's no guessing penalty on the SAT, yet students still leave questions blank. Every empty answer is a guaranteed zero points, while even a random guess gives you a 25% chance of being correct.
How to avoid it: Budget the last minute of each section to fill in any remaining blanks. If you're completely stuck, eliminate obviously wrong answers first, then guess from what remains. Never, ever leave a question unanswered.
4. Not Using Process of Elimination
Many students try to find the right answer instead of eliminating the wrong ones. This approach is slower and less effective. The SAT is designed with tempting wrong answers that seem plausible at first glance.
How to avoid it: Train yourself to cross out wrong answers physically or mentally. Often, eliminating three incorrect choices makes the right answer obvious. In Reading and Writing, wrong answers frequently include extreme language, information not in the passage, or misinterpretations. In Math, wrong answers often result from common calculation errors.
5. Relying Only on Mental Math
Students often make calculation errors because they're trying to do everything in their heads to save time. Simple arithmetic mistakes on questions you know how to solve are frustrating point losses.
How to avoid it: Use your test booklet as scratch paper. Write out your work, especially for multi-step problems. This helps you catch errors and allows you to check your work if time permits. For Math questions, showing your steps also helps you identify where you went wrong when reviewing practice tests.
6. Ignoring the Answer Choices in Math
Many students solve math problems from scratch without looking at the answer choices. Sometimes the answers provide hints about the solution method or allow you to work backwards.
How to avoid it: Glance at the answer choices before solving. If they're all integers, you know you're looking for a whole number. If they're in a specific form (like fractions or radicals), keep your answer in that form. For some questions, plugging answer choices back into the problem is faster than solving algebraically.
7. Not Practicing Under Timed Conditions
Taking untimed practice tests feels productive, but it doesn't prepare you for the pressure of the real SAT. Students who only practice without time limits often struggle with pacing on test day.
How to avoid it: Every practice session should include timed work. Start with individual sections under time pressure, then build up to full-length timed practice tests. Use a timer and stick to it strictly. This builds the stamina and pacing skills crucial for SAT test day success.
8. Skipping the Practice Test Review
Taking a practice test and just checking your score is a wasted opportunity. The real learning happens when you analyze what went wrong and why.
How to avoid it: Spend as much time reviewing your practice tests as you do taking them. For every wrong answer, identify whether you made a careless error, didn't know the content, misread the question, or ran out of time. Create an error log categorizing your mistakes. This targeted review transforms practice tests into powerful learning tools.
9. Cramming the Night Before
Some students think they can make up for weeks of insufficient preparation by studying intensively the night before the SAT. This approach leads to exhaustion, anxiety, and poor performance. Your brain needs rest to function at its best.
How to avoid it: Follow a consistent SAT study schedule spread over weeks or months. The week before the test should involve light review and plenty of rest. The night before, prepare your materials, do something relaxing, and get to bed early. Trust that the preparation you've done will serve you better than last-minute cramming.
10. Not Familiarizing Themselves with the Digital Format
The SAT is now digital, but some students still prepare using old paper-based materials exclusively. The digital format has different navigation, tools, and a different feel that can throw off unprepared students.
How to avoid it: Take all your practice tests using the official Bluebook app from College Board. Get comfortable with the digital interface, built-in calculator, reference sheet, and annotation tools. Practice navigating between questions and sections. Familiarization with the digital SAT format reduces test-day stress and helps you work more efficiently.
Bonus Mistakes to Avoid
Forgetting to bring required materials: Double-check you have your admission ticket, photo ID, approved calculator, and backup pencils.
Arriving late or rushing: Plan to arrive 30 minutes early. Rushing increases anxiety and errors.
Second-guessing too much: Your first instinct is often correct. Only change answers if you're certain you made a mistake.
Ignoring difficult passage types: If science passages or historical documents intimidate you, practice them specifically rather than avoiding them.

Not reading questions carefully is the most common and costly mistake. Students often miss key words like "not," "except," or specific instructions about what the question is asking for, leading to avoidable wrong answers.
How can I avoid running out of time on the SAT?
Practice under strict timed conditions, use the two-minute rule for difficult questions, answer easier questions first, and don't get stuck on any single problem. Regular timed practice builds the pacing skills you need.
Should I guess on SAT questions I don't know?
Absolutely yes. There's no penalty for wrong answers, so guessing gives you a chance at points while leaving it blank guarantees zero. Use process of elimination first to improve your odds.
