What the result means
The result shows whether review is broad enough and whether weak topics are still creating exam risk. High coverage with many weak topics still needs targeted revision.
Revision health = topic coverage × 45% + review depth × 25% + weak-topic control × 30%
Weak-topic control measures how much of the course remains risky even after general review.
Example calculation
Reviewing 18 of 24 topics with 5 sessions and 4 weak topics left gives moderate readiness and a clear need for targeted review.
Tips for better results
- Review weak topics twice before the exam.
- Use spaced repetition instead of one long review block.
- Convert missed questions into a priority checklist.
FAQ
How many revision sessions are enough before an exam?
The number depends on topic count and difficulty, but multiple shorter sessions are usually better than one long session.
What is the best revision schedule?
A strong schedule covers all topics early, then repeats weak topics closer to the exam.
How do I identify weak topics?
Weak topics are the areas with repeated errors, low confidence, or slow solving time.
How much revision should students complete weekly?
Weekly revision should cover new material plus selected older weak topics to prevent forgetting.
Does spaced repetition improve exam scores?
Spaced repetition can improve retention because it forces recall after time has passed.
