Certo: Exam Prep & Practice

100% original questions, no leaked content, no ban risk. Timed mock exams with scaled scores, deep explanations, and spaced repetition. Pass, or your next exam is free.

Certo is the native, offline way to prepare for professional certification exams: 100% original questions, explanations that teach the reasoning behind every answer, and a realistic scaled-score mock exam.

WHY CERTO

• Original questions, zero risk. Every question is written to the public exam outline. No leaked or brain-dump content, so no NDA or ban risk, just legitimate high-quality practice.
• Explanations that teach. Each question shows why the correct answer is right AND why every other option is wrong, so you learn the concept, not just the answer.
• A real exam simulation. Full-length, timed, weighted to the official blueprint, and scored on a 1000-point scale with a 700 pass line and a per-topic breakdown, so you know when you are truly ready.
• Spaced repetition that works. Missed and flagged questions return on an SM-2 schedule, right when you are about to forget them.
• Flashcards, built in and your own. Study key terms and create your own cards that track alongside the deck.
• Offline and private. No account, no sign-up, no data collection. Everything works on the plane.

PASS GUARANTEE Score 700 or higher on a full in-app simulation, sit the real exam within 30 days, and if you do not pass, your next exam is on us.
