Solving Information Asymmetry
Graduating high school in an international program often brings a heavy bureaucratic burden. Students holding a German Abitur need to reason about course constraints, final-exam scenarios, and how a German result translates into the Spanish admissions scale. The calculator puts those connected questions into one inspectable workflow.
The application encodes DSM Abitur constraints, searches eligible course combinations, and applies explicit German-to-Spanish conversion formulas. It reports estimated Abitur points, German and Spanish grades, and optional weighted admissions scenarios without presenting the result as an official admissions decision.
Modern Frontend Architecture
Under the hood, the converter leverages a robust algorithm that evaluates valid course combinations and multiple grading scenarios. Optional admissions subjects and their weights can then be explored separately. The core logic runs client-side, packaged as a fast, offline-capable Progressive Web App (PWA) with a Service Worker.
The user interface was built iteratively using Vanilla JavaScript and Tailwind CSS. Direct DOM manipulation and careful local storage handling ensure that user inputs are instantly saved and restored across sessions.
