I am building an online math practice platform for AMC/AIME styled questions. It is a database-driven question bank that allows students to generate unlimited custom practice quizzes and allows teachers to manage content and assignments. The platform will serve as a long-term repository for thousands of math competition problems written in LaTeX, including diagrams and solutions.
