Challenge
Before

With paper workbooks and generic tools, learners couldn't focus review on their weak points, and pulling out just the needed scope was tedious. No study records remained, so inefficient repetition continued.

  • Focus review only on my weak points
    Managing mistakes by hand / inefficient
  • Extract just the scope I need from a huge pool of questions
    Can't narrow down by field or keyword
  • Do random practice in spare moments
    Paper workbooks are tedious to grade and carry
  • Record study progress and right/wrong results
    Solved questions and scores don't persist
Solution
After

Freely extract questions by hierarchical category + keyword, then auto-repeat weak points across 5 quiz modes. Answer history and favorites are logged per user, building a learning cycle that grows into 'your own study material' the more you solve.
