Know when and how you can use a calculator on the SAT.
Math Section
Understanding the calculator policy for the Digital SAT Math section is crucial for effective test preparation. This guide outlines what is allowed, what is prohibited, and offers strategies to optimize your calculator use during the exam.
Unlike previous paper-based tests, the Digital SAT permits calculator use throughout the entire Math section. This approach reflects the real-world scenarios where calculators are routinely employed. You have two options when it comes to calculator usage:
Built-in Graphing Calculator:
The Digital SAT includes an embedded Desmos graphing calculator accessible within the Bluebook™ testing application.
Personal Calculator:
Students may bring their own acceptable calculator to use during the test.
It is important to note that while calculators are permitted on all Math questions, some problems can be solved more efficiently without one. Knowing when to rely on mental math or simple estimation can help you work more quickly and accurately.
The College Board allows a range of calculators for the SAT Math section. Acceptable models include:
Scientific Calculators:
All models are permitted.
Graphing Calculators:
Most models are acceptable. For example:
For a comprehensive list, refer to the College Board's official calculator policy.
Certain calculators and devices are not allowed due to their advanced functionalities. Prohibited items include:
Using any prohibited calculator during the test can result in dismissal from the exam and cancellation of scores.
To maximize efficiency during the exam, consider the following strategies:
Familiarize Yourself:
Practice with the calculator you intend to use on test day. Familiarity with its functions and interface will reduce errors and save valuable time.
Use Judiciously:
Not every question requires a calculator. Develop the ability to decide when mental math or estimation might be quicker than calculator use.
Know the Tools:
If you use the built-in Desmos calculator, explore its functionalities before test day through practice tests or via the Desmos website.
Backup Plan:
Always bring spare batteries or a backup calculator in case of technical issues.
By understanding the Digital SAT calculator policies and employing effective strategies, you can optimize your performance on the Math section. Make sure to practice with your chosen calculator beforehand and develop a plan for when to use it—and when to rely on other problem-solving methods.
