SAT Test Calculator Programs

The SAT Operating System is an app for TI-83+, TI-83+ Silver Edition, TI-84+, TI-84+ Silver Edition, TI-89, and TI-89 Titanium graphing calculators that solves SAT math problems for you DURING the SAT test. It allows you to work problems faster and with greater accuracy than you ever could by hand or with a graphing calculator alone. It takes your input based on the SAT problem and gives you an answer or solution. It is powered by almost all of the equations, tools, and approaches you would ever need during the SAT math sections. Students typically improve their score by 60 points on the SAT just by using this software. You are permitted to use it during the test under the College Board's official Calculator Policy.
This is the companion app to the SAT Operating System. It allows you to quickly get access to helpful information and support options relevant to the SAT Operating System while studying for the SAT test.
