SAT prep that
starts to click.

Free access includes a diagnostic, one designated full-length practice test, limited Mica messages, and a personal day-by-day study roadmap. The diagnostic and free test are ready to take; the roadmap is view-only, and starting its lessons or practice questions requires a card-backed three-day trial or a paid plan. No card is needed for the free diagnostic or test.

Your diagnostic results, recent answers, and goals help Vertex focus your study plan on the skills that need more attention. Follow that focus or choose a skill, difficulty, and topic for a set of 1–20 questions. Learn from each explanation, return to missed questions, and keep building your understanding. Math and Reading and Writing practice are included with a card-backed trial or paid plan, within usage limits.

Vertex’s in-house content team built the course from an analysis of an archive of 1,900+ official SAT Math questions. Thirty lessons turn recurring question patterns into practical Desmos methods across equations, systems, functions, geometry, trigonometry, and data. Worked examples and concept checks help you learn what to enter, how to interpret the result, and when algebra is the better choice.

The AI tutor helps you work through practice questions and ask follow-up questions about an explanation. You can use it when you're unsure how to begin or want to understand a step more clearly. Like any AI tool, it can make mistakes, so check its reasoning against the question and answer explanation.

The trial lasts 72 hours. After that, your selected plan begins and your card is charged the billing total shown at checkout. We'll email you a reminder before your first payment. You can cancel in Settings before the trial ends to avoid a charge. If you don't see a Vertex email, check your spam or junk folder.

Yes. You can cancel in Settings at any time. Your paid access continues until the end of your billing period, and your previous work stays in your account. For paid enrollments or purchases started on or after September 26, 2026 at 7:00 PM UTC, refunds are generally not offered. You may email a refund request to support@vertex-prep.com; we review each request case by case, and a refund is not guaranteed. Canceling a subscription stops future renewals; it does not by itself refund a payment already made. Your paid access normally continues through the period already paid for. If you began a trial, started a checkout session, or purchased before September 26, 2026 at 7:00 PM UTC, the terms presented at that enrollment or checkout remain in force for that subscription. Where those terms provided it, this includes a full refund of the first subscription payment requested within seven days of payment. Using Vertex during a trial or refund period did not affect eligibility. Consumer rights required by law still apply. See the refund policy.

Yes, you can use Vertex in your phone's browser. A laptop or tablet gives you more room for graphs and timed practice, so we recommend a larger screen for those sessions.
