AdreshSingh/mcq_app_katex — reverse-engineered prompt

Build me a simple React quiz app for multiple choice questions, using this Vite project as the starting point. I want it to feel like a clean study tool where a student can answer MCQ questions, including questions and choices that contain math formulas rendered nicely with KaTeX.

Please include a small set of sample questions so I can test it right away. The user should be able to pick an answer, see whether it was correct, move to the next question, and see a final score at the end. Add a reset button so they can try again. Make the design simple, modern, and readable on both desktop and mobile.

Keep everything local in the app for now, no login or backend needed. If any KaTeX setup details are unclear, look up the current docs online and wire it up properly. Make sure the app runs with the normal Vite dev command.
