During November 2025, Sourab Reddy Shok enhanced the grading rubric for the Asabeneh/30-Days-Of-Python repository by updating documentation to enforce non-overlapping score ranges, specifically clarifying boundaries for grades A, B, and C. This documentation-focused work, written in Markdown, addressed edge-case ambiguities that previously led to confusion and grading disputes among students and instructors. Sourab applied educational content creation skills and maintained strong version-control practices, ensuring that the updated rubric aligned with course requirements and was easy to maintain. The result was improved transparency in assessment criteria, reduced support queries, and a more scalable approach to quality control in grading.
