How should I use the reference sheet and calculator on SAT math?
The math section gives you a reference sheet of common geometry formulas and a built-in graphing calculator the whole time. Use the sheet instead of memorizing what is on it, and use the calculator for graphing and messy numbers — not for simple arithmetic you can do faster in your head.
Learn the sheet before test day so you know what is on it. Students who have not looked at it waste seconds hunting for a formula, while students who have simply glance at it. Memorizing the formulas it already provides is a poor use of study time.
Spend that memory on what is not on the sheet: slope and linear relationships, how quadratics and exponentials behave, exponent and percent rules. Those you will need to recall without help.
The built-in graphing calculator is strongest when a question can be seen. Graphing two equations to find where they meet, or a function to read a maximum or an intercept, can turn a long algebra chain into a few seconds. Practice that move until it is automatic.
It is slowest on simple arithmetic and on questions where a quick estimate or substitution settles the answer. Reaching for the calculator by reflex costs time and invites typing errors. A good rule is to ask first whether it is faster to see it, work it, or type it.
You can also bring an approved handheld calculator if you prefer one you know well. Which models are allowed is set by College Board, so check the current list before test day rather than trusting a rumor. Our page on which calculators are allowed covers it.
Brainrise math drills are meant to be done with the same tools in reach, so choosing between graphing, paper and mental math becomes a habit before it has to be a fast decision.
