Once you’ve answered all questions, you’ll see your final score displayed as a percentage. The app automatically tracks your performance for each domain.

​
Performance Tracking

Your most recent score for each domain appears as a circular progress indicator on the domain card:
  • Green circle (80%+): Strong performance - you’re ready for this domain
  • Red circle (<80%): Needs more study - review the concept map and retake the test
AWS recommends scoring at least 80% consistently before taking the real exam. Use the color-coded indicators to identify which domains need more attention.

​
Study Tools During Tests

Mark questions for review by clicking the flag icon at the top of any question. Flagged questions appear highlighted in the navigation grid at the bottom.Use flags to:
  • Mark questions you want to review again
  • Highlight tricky concepts
  • Create a custom review list
During a domain test:
  • Previous button: Only available for unanswered questions (you can’t go back to answered ones)
  • Next button: Moves to the next unanswered question
  • Continue button: Submits your answer and shows immediate feedback
Once you submit an answer in domain mode, you cannot change it. Take your time before clicking Continue.

  2. Read explanations carefully - The immediate feedback includes valuable learning content
  3. Retake until consistent - Keep practicing each domain until you consistently score 80%+
  4. Use the concept map - Reference the interactive concept map (from the main menu) to understand domain relationships
