Automating Finals Math: How Gemini Vision Powers a Grade Calculator

This project solves a genuine student pain point — the tedious grade calculations every semester — by automating the process with AI-powered PDF parsing. Beyond the practical tool, it demonstrates production-grade patterns for integrating vision-based AI: transparent error handling for uncertain extractions, graceful fallbacks when API quotas hit, and thoughtful UX touches like cycling status messages during long operations. Developers building AI features will find valuable lessons in how to handle uncertainty, manage user expectations, and balance feature richness with simplicity.
