What OnePrep is

OnePrep is an exam preparation platform for Digital SAT, ACT and AP exams. It combines practice questions, full-length tests, score analytics, study planning and AI-supported explanations. The platform lists a 4,000-question bank, revision plans and adaptive practice. Its study plan uses a student's test date and recent activity, then adjusts as accuracy changes. Analytics show accuracy by topic, pacing and difficulty band. Students can export study blocks to Google Calendar or Apple Calendar, and use OnePrep on the web, iPhone, Android or Mac. The free plan costs nothing, requires no credit card, and includes 500 expert-written questions, one full-length practice test and 20 orbs, with 10 more each week. Plus is listed at $148.30 a month as a one-time payment for access through October 4, 2026; it includes 4,000+ questions, two full-length practice tests and three question rush sessions per week. Pro is listed at $165 a month, also as a one-time payment for access through that date, with 4,000+ questions, 300+ challenge questions and six full-length practice tests. OnePrep serves individual students, families, tutors and schools; schools and tutoring teams can contact it for tailored bulk pricing.
