The Course
Every Digital SAT student has Desmos built into the testing app — but most never learn to use it well. This course fixes that.
You'll master the interface, then learn to graph linear, quadratic, and exponential functions on sight; solve systems and inequalities; read intercepts, intersections, and key features straight off the graph; build tables; and run regressions to recover unknown constants.
Every technique is taught on official-style questions, so you're practicing the exact moves the test rewards.
By the end you'll be faster and more accurate, with a clear rule of thumb for when to graph, when to compute, and when to estimate.
The goal isn't tricks — it's a repeatable, low-stress process you can trust under time pressure.
What you will learn
The course follows a deliberate path: get comfortable in Desmos, build calculator fluency, then work through the core SAT question types one at a time.
Lessons are short and example-driven, sequenced so you earn early wins while building skills that hold up on the hard questions.
You'll always know what to focus on, why it matters, and exactly how to use it on test day.

Your instructor
I'm Rob Pollak, and I've spent years helping students turn test-day dread into something that actually feels manageable. Most of my students don't walk in loving the SAT — they walk in stressed. My job is to hand them tools concrete enough that the nerves have somewhere to go. Desmos is one of the best of those tools, and almost nobody uses it to its full potential.
That's why I built this course. The digital SAT puts a graphing calculator right in the testing app, and knowing how to use it well can turn a hard problem into a ten-second one. I teach it the way I teach everything — one clear move at a time, on real questions, building from white belt to black belt — so that by test day the calculator feels like second nature and you can walk in calm, confident, and ready to work.
Interactive
Learn by doing — every technique demonstrated on a real SAT question you can follow along with.
Strategic
Workflows that turn multi-step algebra into a few taps, so you save time where it counts.
Visual
Graph-first methods that make abstract problems concrete — so the answer is something you can see.
