What the result means
The result shows the remaining mistake-review workload and whether the daily correction load is realistic.
Remaining Review = Wrong Problems − Reviewed Problems. Daily Review = Remaining Review ÷ Days Remaining.
Difficult problems may require more than the average review time.
Example calculation
With 30 wrong problems, 8 reviewed, and 7 days left, you need to review about 3.1 problems per day.
Tips for better results
- Review mistakes before starting new problem sets.
- Group repeated error types together.
- Add more time for conceptual mistakes.
