Let’s get you unstuck.

AWS DOP-C02 PREP runs on iPhone and iPad with iOS/iPadOS 17 or later. The interface is available in English and Vietnamese; switch it in your profile. Question text and source explanations remain in English.

No account is required. Bundled question text and local practice work offline. Some source illustrations are loaded from remote image URLs and need internet. The app does not include ads or in-app purchases.

An App Store download link has not been published on this website yet. For availability information, email the developer. Do not install unverified copies from third-party sites.

A practice exam has 80 questions and a 170-minute time limit. It uses a saved deadline, so the clock keeps running when you leave the app. When time expires, the session is submitted. You can navigate between questions and flag them for review before submitting.

No. The 75% threshold is only an in-app practice target. The app grades all 80 practice questions equally and does not reproduce AWS’s scaled scoring or unscored items. A practice result is not a certification result or a pass guarantee.

Send the practice-set name, the question text or a screenshot, the answer you think is correct and a reference if available. The source bank has not been independently verified. It contains repeated prompts with different choices, and one record without an answer key is excluded from practice. Cross-check important concepts with official documentation.

There is no in-app cloud sync or account-based recovery. Study history and saved sessions stay on the device. Deleting the app may permanently remove local progress; do not delete it as a troubleshooting step unless you accept that data loss. Apple device backups are managed separately in your device settings.

Check that your planned exam date is in the future and reminders are enabled in the profile. Then check the app’s notification permission in iOS Settings. Focus modes and notification summaries can affect when a reminder appears.
