SIX FULL-LENGTH TIMED MOCK EXAMS. 435 practice questions, every single one explained. Complete preparation for the AWS Certified AI Practitioner (AIF-C01) exam - free, offline, and with no account, no subscription and no ads. SIX FULL MOCK EXAMS, NOT SAMPLE QUESTIONS Six separate 65-question exams, each timed to 90 minutes, exactly like the real sitting. Every exam is weighted to the official domain blueprint - Fundamentals of AI and ML, Fundamentals of Generative AI, Applications of Foundation Models, Guidelines for Responsible AI, and Security, Compliance and Governance - so your score reflects the exam you will actually face. That is 390 exam-standard questions on top of the practice bank. EVERY ANSWER EXPLAINED All 435 questions explain why the correct answer is correct and why each other option falls short. Learning to see through the distractors is usually what separates a pass from a near miss. ALSO INSIDE - 15 study chapters covering all five exam domains - A 435-question practice bank you can filter by domain to drill a weak area - 72 flashcards for fast terminology recall - A 72-term glossary, filterable by domain - A review queue that collects what you got wrong, flagged, or still need to revisit BUILT AROUND THE REAL EXAM Exam mode runs a full 65-question sitting against a 90-minute timer that keeps counting correctly even if you leave the app and come back to it. Practice mode is untimed so you can work through explanations at your own pace. A STUDY SHELL, NOT A SINGLE-EXAM APP Study Center is built around certification packs. Chapters, glossary, flashcards, practice bank and mock exams are all driven by the pack you are studying, so the same study flow carries across AI certifications from any provider rather than being rebuilt for each one. STUDY OFFLINE All content ships inside the app. No connection is needed to read a chapter, run a mock exam, or review a flashcard. PRIVACY Your progress stays on your device. The app collects no personal data, contains no analytics or tracking, and requires no sign-in. MORE ON THE WAY More premium app features, more exam providers, and more certification courses are coming soon. Study Center is an independent study aid.
