saimanjusha257/Academic-ERP-System ? reverse-engineered prompt

Build me a college ERP web app for admin, faculty, and students, with a clean modern UI and proper login for each role. I want users to sign in with JWT, then see the right dashboard based on their role.

The admin should be able to manage students, faculty, and other admins, add departments and subjects, post notices, and update their own profile and password. Faculty should be able to manage attendance, create tests, upload marks, and update their profile and password. Students should be able to log in, view their attendance, marks, subject list, and update their profile and password.

Please include form validation and clear error messages, and make the whole thing feel polished and easy to use. If anything is unclear, check the current docs online first and then build it in a way that works well with a MERN stack app. Also, set it up so a dummy admin account exists for testing.
