  3. Battery Life: Opt for a calculator with a long battery life to ensure it lasts throughout the entire SAT without any issues. It’s advisable to bring extra batteries or a backup calculator, just in case.
  4. Display: A clear and easy-to-read display is important, especially for quick calculations during the test. Make sure the calculator’s screen is not too small, and the digits are easily readable.
  5. Functionality for Math Section: Check that the calculator has the necessary functions for the Math section of the SAT, such as trigonometric functions, square roots, and basic statistical functions. Some questions may require specific mathematical operations, so it’s important to have a calculator that can handle them.
