HOAIAN2/college-quiz-app — reverse-engineered prompt

Build me a college quiz web app using Laravel and React, with a clean admin dashboard and a separate exam taking screen for students.

I want admins or teachers to be able to manage students, courses, questions, exams, and basic settings. They should be able to create questions, group them into courses or exams, and see the main information from a dashboard. Students should be able to open an exam, answer questions in a simple interface, and submit their work without confusion.

Please set it up so it works with MySQL or MariaDB, includes seed data for testing, and has a basic demo mode password setting. Make the UI practical like a school project, not overly fancy, but still neat and responsive. Also include the setup scripts or clear commands to install, migrate the database, seed data, build the frontend, and run it locally. Use current docs online if needed.
