Your personal study trainer for the SAT^® & ACT^{coming soon}

MastaPrep is a test prep platform that helps students raise their SAT^® scores with a personal study plan, a large practice bank, 10 full-length digital practice tests, vocabulary training and worked explanations for every question. Your plan is built around your areas of improvement and updates automatically as you improve.

Yes. The free plan needs no credit card. It includes four starter skills with five questions each, five vocabulary words and Reverse Recall, one full-length practice test, a placement check, review and a study calendar. Paid plans unlock the full practice library and every test.

Questions, explanations and practice tests are drafted with AI tools against the official SAT^® skill taxonomy, then checked by editorial review for the correct answer, the reasoning, wording and diagrams before they are published. Every question has a report button; anything flagged is pulled and re-checked.

Both. If you're just starting out, MastaPrep begins with a placement check across the tested domains and builds a plan that starts broad and narrows as your practice reveals strengths and weaknesses. If you're retesting, your first practice test sets the plan to your weak areas from day one.

Khan Academy is a strong free starting point, but it has no adaptive plan that follows you. ChatGPT has no scored practice tests, no tracked progress and no spaced review. MastaPrep gives you a scheduled plan, timed tests, mistake review and progress tracking in one place — and explains every answer.

We don't promise a number. Consistency and structured practice are the biggest drivers of improvement, and MastaPrep is built to make consistency easy: short daily sessions, review that comes back at the right time, and a plan that changes as you do. Your score estimate on MastaPrep is our own; it is not an official College Board score.

A student can send you a payment link. You see the price and renewal terms, receive the receipt and can manage the subscription. Students aged 14–17 are asked for a parent or guardian's permission during sign-up.

Every paid plan starts with a 3-day free trial: nothing is charged until it ends, and cancelling before then means you are never charged. After that, cancel renewal any time from Settings and paid access continues until the end of the period you paid for. Mandatory consumer rights remain available.
