edu - Guided Learning Paths
Role
cp4cpp.com/edu is for guided lessons, learning paths, and classroom-oriented content.
It separates learning order from the handbook so learners can study in a coherent progression instead of jumping through isolated articles.
Preface preview

Purpose
- Separate learning-oriented content from reference docs.
- Grow each topic step by step, from small examples to complete templates.
- Guide students from first exposure to harder problems and confident contest solving.

Learning Style
DFS-like learning: users follow a path whose lessons depend on earlier lessons and raise difficulty over time.
Strengths To Preserve
- Guided paths reduce confusion for beginners and save review time for advanced learners.
- Progress signals help people study steadily with a coherent roadmap.
Weaknesses To Fix
- Platforms often point to problems without explicitly modeling what skill changed after solving them.
- Every new lesson implies prerequisites, exercises, progression logic, and update cost.
CP4CPP Rules
- Each lesson should state prerequisites, target skills, practice tasks, and next steps.
- Each problem should have nested and consistent subtasks when later subtasks are strict supersets.
