Worked on the HWTeng-Teaching/202409-Math-Stat repository to enhance content organization and maintainability within the Math-Stat module. Delivered a feature that standardized file naming by renaming HW1022_Q2.md to HW1022Q2.md and updated the file with a formal question title and media references for parts A, B, and C. Focused on documentation using Markdown, applying content filtering to ensure only relevant material remained. No bugs were reported during this period, reflecting a maintenance-oriented approach. The work improved content accuracy and streamlined future updates, supporting a better learner experience and reducing ongoing maintenance effort for the course materials.
