Desmos Mastery for the Digital SAT

The built-in Desmos graphing calculator is the most underused advantage on the Digital SAT. Most students treat it like a basic calculator. This course teaches you to use it like a power tool: solving systems, graphing inequalities, checking answers, and eliminating entire categories of algebra mistakes.

What you'll learn

• Graph both sides of any equation and read the intersection, with no algebra required
• Use tables and function notation to plug-and-check answer choices in seconds
• Solve systems of equations visually instead of by substitution or elimination
• Use sliders to understand how parameters shift graphs on transformation questions
• Build a personal calculator policy: when to use Desmos and when to skip it
• Avoid the three Desmos mistakes that cost students the most points
