Digital SAT Mistakes Costing You 100+ Points in 2025

1. Reading Questions Too Quickly

Rushing through SAT Math questions in the 2025 digital format can seriously hurt your performance. SAT expert Dora Seigel points out, "Most SAT Math questions will have an answer choice that will seem correct if you misread the question". This is especially true for multi-step problems that require extra attention.

Studies show that reading too quickly without fully understanding the question often leads to wasted time rereading. Here are three strategies to help you stay focused and avoid common traps:

• Highlight Key Details: Before diving into the solution, underline or mark important numbers, variables, and conditions. This helps ensure you don’t miss anything critical.

• Make Predictions: Try to estimate the answer before looking at the options. This can help you steer clear of answers designed to mislead.

• Manage Your Time: Spend up to one minute per question to ensure you understand it fully before moving on.

"One of the main reasons that students make careless errors on SAT math problems is that they are so worried about getting to the end of the section that they are not focusing on the problem in front of them."

• Dr. Steve, Get 800

For tougher, higher-numbered questions, if an answer seems too obvious, take a second look. Eliminate that choice and carefully recheck the details. Don’t hesitate to reread questions to make sure you’ve captured all the important information.

2. Not Using the Desmos Calculator

The digital SAT in 2025 includes a built-in Desmos calculator, but many students don't take full advantage of it. Studies reveal that about one-third of SAT Math questions can be solved faster using Desmos, which can help improve your score.

Here’s how Desmos can make tackling math questions easier:

For instance, if you're finding the y-intercept of a function, just type the equation into Desmos. Let’s say the equation is g(x) = x² + 8. By hovering over the y-axis, you’ll instantly see the intercept at (0, 8). This approach saves time compared to solving it algebraically.

Experts emphasize using Desmos strategically:

"The main message that I want to get across is that you are the one taking the test, not Desmos. So, use Desmos wisely. Use that tool to fight with you, not fight for you."

Here are some tips to get the most out of Desmos:

• Master the Basics: Practice graphing lines, parabolas, and other functions to build speed.

• Use the Slider Feature: Adjust variables to see how they change the graph.

• Identify Key Points: Spot intersections, minimums, and maximums quickly.

Desmos is particularly helpful for systems of equations. Enter two equations, and you can immediately see parallel lines or intersection points using the graphing feature.

It also offers tools for copying equations and includes functions for calculating mean, median, range, and trigonometric values. Familiarize yourself with these features to save time and improve accuracy during the test.

3. Running Out of Time

About 40% of test-takers struggle to manage their time effectively during the SAT. The 2025 Digital SAT Math section gives you 95 seconds per question in two 35-minute modules, each with 22 questions. To perform well, you’ll need to balance quick problem-solving with smart time management.

Each module allows 35 minutes for 22 questions, adding up to 70 minutes for the entire Math section. Many SAT Math problems can be solved in under 60 seconds if you’re well-prepared. However, students often spend too much time on tough questions early on, leaving less time for easier ones that could boost their score.

Here are some strategies to help you manage your time:

• Set Mini-Deadlines: Aim to finish the first 11 questions in about 17 minutes, giving yourself an equal amount of time for the remaining questions. This keeps your pace steady throughout the section.

• Skip Strategically: If a question takes too long, mark it and move on. Focus on securing points from simpler problems first.

Keeping calm under pressure is just as important as pacing. Research shows that staying composed can greatly improve performance. Instead of getting stuck on lengthy problems, prioritize the ones you can solve quickly.

To sharpen your timing skills:

• Practice in simulated test conditions to develop a natural sense of pacing.

• Identify and work on problem types that consistently slow you down.

• Use digital tools like the built-in timer and Desmos calculator effectively.

• Monitor the timer regularly, but don’t let it distract you.

Above all, stay steady under time pressure. Your pacing strategies should align with the digital format’s structure and tools.

4. Missing Easy Points Through Answer Elimination

A common yet often ignored strategy for the SAT Math section is using answer elimination systematically. Many students dive straight into solving for the exact answer, but you can save time and improve accuracy by first ruling out incorrect options. Here’s how elimination can work in your favor.

If you're stuck on a problem, start by eliminating answers that are obviously wrong. With four choices, removing just one increases your odds from 25% to 33%, and eliminating two bumps it up to 50%.

Here are four effective elimination techniques for SAT Math:

• Plugging in Answer Choices: Instead of solving a complex equation, plug each answer choice into the problem. Eliminate any that don’t meet all the conditions.

• Testing Mathematical Models: Use sample values to test the expected relationships. For example, if a question involves height changes between ages 2 and 5, substitute those ages to see which option aligns with the trend.

• Using Real Numbers: Replace variables with simple numbers to make the problem easier. For instance, in an expression like 11(x+2) + 1(x+3) where x > 3, plugging in 5 for x can help you quickly test each option.

• Checking Signs and Operations: Pay close attention to signs. For example, when adding complex numbers like (7 + 3i) and (–8 + 9i), you can immediately eliminate any results with incorrect signs.

"You should always use the process of elimination as much as you are able to increase your chances of getting the right answer." - Ellen McCammon

Elimination isn’t just about improving your odds when guessing - it’s about working smarter. By quickly discarding impossible answers, you can focus your time on analyzing the remaining choices. This strategy works especially well for algebra, modeling, and expression-related questions.

To get the most out of this approach, read the entire question and all answer choices carefully before jumping into calculations. Look for obvious errors or contradictions that can help you eliminate options right away. This saves time and helps you avoid falling for trap answers.

5. Making Simple Calculation Errors

When every second matters during a test, accurate arithmetic is just as important as quick thinking. Careless mistakes in calculations can cost you valuable points, just like misreading a question or poor time management.

Under pressure, even small math errors can lead to incorrect answers. For example, instead of subtracting 1.75 from 2.35, rushing might cause you to add them instead, producing the wrong result.

"This is arguably the easiest mistake to fix. Write out all your steps, and you'll never accidentally get a question wrong because you skipped a step!" - Dora Seigel, SAT Math Tutor

The Navy SEALs' saying, "Slow is smooth, and smooth is fast", applies perfectly to SAT Math. A steady, deliberate pace often leads to better accuracy and efficiency than rushing through problems.

For more complicated problems, break them into smaller, manageable steps. This method not only minimizes errors but also makes it easier to catch mistakes during review.

Tips to Avoid Common Errors

Recognizing patterns in your mistakes can help you refine your approach. Use these practical techniques to stay on track:

• Double-check each step for accuracy.

• Write out every step, even for simple calculations.

• Verify numbers before entering them into your calculator.

• Focus on one step at a time, instead of rushing ahead.

These small adjustments can make a big difference in your test performance.

6. Picking Trap Answers

The SAT Math section is full of pitfalls designed to trip up students who overlook key details. Spotting these traps is essential to avoid losing points on questions you could have answered correctly.

One common pitfall is the "Solve for X" mistake. This happens when students instinctively solve for x without checking if that's what the question actually asks. For instance:

"If 5x - 2 = 3x + 4, what is the value of 2x?" Solving for x gives x = 3, but the correct answer is 6, because the question asks for 2x.

Common Trap Types and How to Avoid Them

"One of the best ways to avoid small mistakes is to know the types of questions in which the SAT employs traps to trick you..."

Graph-based questions, in particular, often include subtle traps that require extra attention.

How to Handle Graph-Related Traps

Graphs can be sneaky. Pay close attention to:

• The scale on each axis - ensure they're consistent.

• Where the axes intersect - confirm it's at (0,0) unless stated otherwise.

• Whether both axes use the same scale.

• Any small details that might mislead you visually.

Tutors often warn that SAT questions are crafted to exploit rushed thinking and gut reactions. To avoid falling for these traps:

• Write out every step, especially for questions where calculators aren't allowed.

• Double-check that you're solving for what the question actually asks.

• Look at your final answer and ask, "Does this make sense in the context of the problem?"

As questions get harder, traps become more subtle. Answers that seem obvious might be planted to catch students who skim through without careful analysis. By consistently applying these strategies, you'll improve your ability to tackle tough questions with confidence.

7. Rushing Through Multi-Step Problems

Multi-step problems on the Digital SAT Math section demand careful attention and a methodical approach. With roughly a minute per question, it's tempting to rush through challenging problems, but this often leads to mistakes that could have been avoided.

The Hidden Cost of Rushing

Rushing through problems can lead to errors at every stage of the process:

"When you're rushing, you're not paying full attention to each step as you're doing it. You've lost your focus. And when you lose your focus, you're much more likely to make a mistake." - Jeff, SATSuccessSecrets.com

Breaking Down Problems Effectively

To tackle multi-step questions, it's essential to take a structured approach. Start by identifying the key details and planning your solution step by step.

Here’s how to approach complex problems:

• Underline unknowns and circle the given data to organize your thoughts.

• Identify the mathematical concepts or formulas needed to solve the problem.

• Instead of erasing mistakes, cross them out to leave a record of your work.

This method reduces confusion and helps you stay on track.

Time Management Tips

For complicated problems, managing your time wisely is crucial. Some strategies include:

• Focusing on simpler questions first to secure easy points.

• Using estimation to quickly check if your answer makes sense.

• Marking uncertain questions for review if time permits.

"Take the time to read the question fully, circle the important information, and make sure you know what you're being asked before you start doing any work." - Dora Seigel, PrepScholar

Smart Calculator Use

When using tools like Desmos during the digital SAT, precision is key. Follow these tips to avoid calculator-related errors:

• Double-check your number entries.

• Pay attention to decimal points and parentheses placement.

• Review your final answers to ensure they make sense in the context of the problem.
