This project analyzes a sample student marksheet to uncover performance patterns and guide improvement. The problem addressed is that schools often record grades without extracting strategic insights, leaving gaps in identifying weak subjects, class trends, and equity issues. The audience includes teachers, administrators, and policymakers seeking data-driven decisions. Using Microsoft Excel for cleaning, formulas, charts, and statistical tools such as regression and ANOVA, the project highlights subject difficulty, class benchmarks, and gender-based differences. By transforming static marksheets into dashboards and KPIs, the project empowers schools to allocate resources effectively and enhance student success.
