About this project

Win That Glass!

This tool was built to help you crush your competitive events.

Strategy to Win

Practice Daily: Consistency is key. Even 10 questions a day helps.
Review Explanations: Don't just check if you're right. Understand why.
Submit & Verify: Use the "Submit" button to commit to your answers before seeing the result.
Focus on Weaknesses: Use the summary to identify areas where you struggle.

Built for the DECA community.
