Study Tips

Reserve two weekly deep-work sessions for code quality review, refactoring, and cross-browser/platform testing.
Maintain a technical debt ledger tracking complexity hotspots, test gaps, and performance bottlenecks requiring attention.
Run weekly code review discussions, learning from peer feedback and measuring code quality metrics (coverage, maintainability index, cyclomatic complexity).

Study Tips for Success

Protect consistent weekly practice time and complete hands-on work before moving to the next topic.
Document implementation decisions, trade-offs, and lessons learned after each weekly deliverable.
Review feedback quickly and ship an improved revision within the same week to reinforce retention.
Track measurable progress with checklists, test evidence, and milestone outcomes.
