This is a web application that i built for Addis Ababa University when i was working for a company called Farka ICT Solutions and has different roles like Test Taker, Test Developer and Admin and different exam section each exam section has it's own time and when test takers take that exam they system will start to count the time and when the time is up it will automatically redirect them to the next exam section. This app allows test takers to take University entrance exam and show them their result when they finish the examination process. Test developers can create and modify different types of exams, exam questions and exam sections. Admin users can manage users (Test Takers, Test Developers and Admins), schedules and other administrative tasks.
I can't provide the demo link and source code for this app because they are using it on there own LAN server and for security reasons. If you want to see how this app works we can set up a meeting and I will present you the whole system.
