2) Module selection and verification: The program must authenticate the student access using student ID and password.

Students should be able to choose two different modules out of the following modules (more than two modules is not possible):
Programming 1
Programming 2
Networking 1
Mathematics

Students should be able to view their current selected modules.

The program should allow the user to return to the main page.

3) Student account top-up:
The program must authenticate the student access using student ID and password.

Students should be able to deposit points in his/her point account. The program should confirm the requested points with the user before adding them into his/her account.

The program must return to the main page.
