sudeshsudhii/College-Management-System-project ? reverse-engineered prompt

Build me a college management system where an admin, teachers, and students each have their own login and dashboard. The admin should be able to manage the college setup, classes, subjects, teachers, students, and post notices for everyone. Teachers should be able to see their assigned classes, mark attendance, upload exam marks, and view their subjects. Students should be able to see their profile, attendance, marks, results, enrolled subjects, and send complaints to the administration.

I want it to feel like a real school portal, simple to use, and organized with clear pages for each role. Use a modern clean dashboard style, and make the data update properly across the app. Connect the frontend and backend, store everything in MongoDB, and handle login securely with role based access. If you need to check any current library docs while building it, feel free to look them up online.
