deepakvish001/Pariksha-Platform ? reverse-engineered prompt

Build me a clean modern exam practice app called Pariksha Platform.

I want a student friendly website where users can sign in, browse available tests, start a quiz, answer questions one by one, and see their score and review mistakes at the end. Include a simple dashboard with upcoming tests, past attempts, and progress over time. If it fits, add an admin area where someone can create tests, add questions, set timers, and publish or hide exams. Make it feel polished and easy to use on mobile too.

Use the existing React app, keep the design light and professional, and connect the data to Supabase if that is already set up in the project. Add sensible empty states, loading states, and basic validation so it feels complete. Please make sure the main flows work end to end, and look up current docs online if you need to.
