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 — 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
