TestPrepOS

TestPrepOS is an AI-powered test preparation platform built for serious GMAT, GRE, & SAT students. Designed from the ground up for iPad, it combines adaptive practice, real-time AI feedback, and a digital canvas into one focused study environment. PRACTICE WITH PURPOSE Work through hundreds of Quantitative & Verbal problems. BUILT-IN CANVAS Solve problems the way you think — write out your working directly on iPad with Apple Pencil or your finger. The canvas supports pen and eraser tools with palm rejection, so you can focus on your workings. AI TUTOR ON DEMAND Stuck on a problem? Ask for a hint and get a targeted nudge — not the full answer. After you submit, get a detailed explanation of the solution. The AI adapts to your approach and helps you build intuition, not just memorise steps. VOICE TUTORING Have a spoken conversation with the AI tutor. Talk through your reasoning, ask follow-up questions, and get real-time feedback — like having a private tutor who can see your work available whenever you study. PHOTO FEEDBACK Photograph your handwritten work and get instant AI analysis. The AI tutor reads your working and provides live feedback. TUTOR INTEGRATION If you work with a human tutor, they can assign specific problems, annotate your canvas work, and track your progress through their own dashboard. TestPrepOS bridges the gap between self-study and guided instruction. LEARNING INSIGHTS An AI-generated learning profile identifies your strengths and weaknesses so you know exactly where to focus.
