Feasibility of my project.

[Smith08]

Hi. I am currently studying computing and must create a project that successfully uses a GUI , stores data etc. and it must solve a problem. I thought of creating a program which when run opens a GUI and allows you to register/ log in. There will be 2 divisions of users, teachers and students. With different permissions. The program will be a maths quiz. So students will be able to complete quizzes. Their scores will be stored in a database along with the date they completed the quiz. The teachers will be able to view this data.
Is it possible to create the teacher/student user permission levels?

At that point it's just a matter of a few if's in your code, it it's just a toy project with a local DB. A real-life project would be different, with the database out of reach of students (ie, we are taking about web application on  aback-end server and such).

If so, is it a complex project idea? I am an A level student and I have a few months to complete this.
Thank you.

Not if it's a toy project.

Thanks for the reply. I'm not quite sure what you mean by 'toy project'. The project is supposed to solve a real world problem. It is meant to work in an actual classroom to be used by a class. I am simply making up a fake client. Thanks again.
Also, how many lines do you think the code would be. Of course there are various approaches but would it be in the 100s, 200s?
