**The First and Most Comprehensive SAT-Oriented Desmos Course**

#### Let us show you how to use the Desmos graphing calculator to rapidly solve problems on the Digital SAT

**We begin at the Beginning, but You Can Dive In Anywhere**

You’ll learn **everything you need to know** about using Desmos on the Digital SAT, starting with the nuts and bolts, but if want to get right to the worked examples, jump right into any topic and explore the course however you like

**All the Details, Explained and Illustrated**

We don’t just tell you how to use the tools in Desmos; we **show **you, with clear, well-marked pictures of just what you’ll see in the Desmos user interface

**Includes Hundreds of Interactive Live Graphs**

This isn’t a text book that just sits there, or a bunch of videos that show you someone else using Desmos—it’s **an interactive experience** that includes hundreds of carefully-crafted interactive live Desmos graphs

**Hundreds of Example Digital SAT Problems, Solved**

The course methodically goes through **every type of Digital SAT problem** for which you can use Desmos, with each topic containing realistic example problems and live Desmos graph solutions
