ExamPredictor Reliability Update

ExamPredictor Reliability Update

We focused on the parts of ExamPredictor that matter most after a learner starts: keeping progress available, keeping access state accurate, and recovering cleanly when a backend dependency is temporarily unavailable.

• Improved loading and saving of courses, topics, missions, practice questions, mock exams, readiness, streaks, and achievements.
• Hardened written-answer grading and answer submission so learning progress is less likely to disappear after a slow or interrupted request.
• Improved subscription and entitlement synchronization so the learning workspace reflects the user's actual access state.
• Added safer handling for missing or incomplete learning records and existing users moving into the new workspace.
• Improved database retry, connection handling, and error responses so transient failures are clearer and recoverable.
• Expanded automated coverage around learning-engine persistence and API behavior.

ExamPredictor should now feel more like a dependable learning workspace: progress is preserved, access is clearer, and failures explain what to do next.
