Question 1

Is Prism Prep free?

Accepted Answer

Yes. Prism Prep is 100% free during beta, with no credit card required. That includes the full lesson pathway, the practice question bank, the diagnostic test, progress tracking, and the Desmos calculator tutorial. There is no paid tier gating the core study material.

Question 2

Does Prism Prep cover the Reading and Writing section, or only Math?

Accepted Answer

Both. The lesson pathway covers all eight domains the digital SAT tests. On the Math side that is Algebra, Advanced Math, Problem-Solving and Data Analysis, and Geometry and Trigonometry. On the Reading and Writing side it is Information and Ideas, Craft and Structure, Expression of Ideas, and Standard English Conventions. Every subtopic within those domains has its own lesson.

Question 3

How does Prism Prep work?

Accepted Answer

Take a short diagnostic to find which skills are costing you points. You then get a lesson pathway of 28 nodes covering every SAT domain. Each node opens on a video lesson for that skill, followed by practice questions drawn from that exact skill. Nothing is locked, so you can jump straight to the domain you are weakest in rather than working through in order.

Question 4

What is the Desmos tutorial?

Accepted Answer

A free interactive tutorial that teaches you to use the Desmos graphing calculator built into the digital SAT. It covers the shortcuts that turn multi-step algebra problems into a single graph, such as solving systems by intersection and reading zeros directly off a parabola. No account is required to try it.

Question 5

Do I need an account to use Prism Prep?

Accepted Answer

You can try the Desmos calculator tutorial without an account. To take the diagnostic, work through the lesson pathway, practice the question bank, and have your progress saved, you need a free account. Signup takes an email address or a Google login.

Question 6

Is Prism Prep built for the digital SAT?

Accepted Answer

Yes. Practice runs in a test interface modelled on the real digital SAT, including the built-in Desmos graphing calculator, so the format is familiar on test day. The question bank and lesson content follow the College Board domain and skill taxonomy for the current digital test, not the retired paper SAT.
