SAT Calculator Policy Chart

The SAT allows calculator use throughout Math. The built-in Desmos calculator changes how students should solve many problems.

Calculator rules overview

Always check current College Board rules before test day, especially if bringing a personal calculator.

Calculator optionAllowed?Best use
Built-in DesmosYesGraphing, tables, systems, regressions
Approved personal calculatorYesFamiliar backup
Phone calculatorNoNot allowed
CAS calculatorCheck policyMay be restricted

Strategy

Use Desmos when it saves steps. Use mental math when opening the calculator would take longer than solving.

How to use this on real SAT questions

The important policy point for prep is simple: calculator use is available throughout Math, so practice calculator-first decision making before test day.

  • Bring a personal approved calculator only as backup.
  • Use the built-in Desmos for graphing, tables, and regression.
  • Do not waste time opening Desmos for arithmetic you can do faster mentally.
  • Practice with the same workflow you will use in Bluebook.

How to turn this into SAT Math points

For Math resources, the useful question is always: which setup gets me to the answer fastest? Decide between mental math, paper algebra, Desmos, or answer-choice testing before you start calculating.

  • Use Desmos for intersections, roots, vertices, tables, and regression.
  • Use paper algebra when the equation is short or already factored.
  • Use answer choices when they are ordered and easy to substitute.
  • After every miss, label it as setup, algebra, calculator, or reading error.
