SATMock Now Has a Built-In Desmos Calculator
Starting today, every SATMock mock test and free quiz includes an integrated Desmos graphing calculator during math sections — the exact same calculator you get on the real Digital SAT.
Why This Matters
On the real Digital SAT, College Board provides both a Desmos graphing calculator and a scientific calculator for all 44 math questions — students can toggle between them. It's not optional — it's part of the test interface. Yet no other SAT prep platform — not Khan Academy, not Kaplan, not Princeton Review, not UWorld — gives you access to Desmos during practice.
That means students have been practicing math in a fundamentally different environment than the real test. Until now.
How It Works in SATMock
-Mock Tests: When you reach Math Module 3 or 4, a calculator button appears in the header bar. Click it (or press Ctrl+Shift+C) to open the Desmos panel.
-Free Quiz: The calculator automatically appears for math questions.
-Two modes: Toggle between Graphing and Scientific calculators — just like the real SAT gives you both.
-Desktop: The calculator opens as a draggable floating panel so you can position it wherever works best.

-Mobile: The calculator opens as a full-screen overlay, just like the real Bluebook app.
Your calculator state persists across questions within a module. When you move to the next math module, it resets — exactly like the real SAT.
How to Use Desmos on the SAT
If you haven't used Desmos before, here are the most powerful strategies:
1. Graph both sides of an equation — type y = 2x + 3 and y = 5x - 1 to visually find the intersection (solution)
2. Check your algebra — solve a problem by hand, then plug your answer into Desmos to verify
3. Visualize quadratics — instantly see the vertex, roots, and direction of a parabola
4. Plot scatter data — for statistics questions, enter data points to check trends
5. Use sliders — Desmos auto-creates sliders for undefined variables, letting you explore how parameters change a graph
