Mahidol timetable

This app starts with the problem that everysemester we need to make our own timetable in excel ourselves as our university does not provide a proper timetable system. Would it be better if we have an app that can auto-generate time table for us as well as add to google calendar for convenient use and get notifications before classes? here is a demo of Mahidol timetable desktop app.

The overall project structure is shown in the diagram below.

The program was written in JAVA and was built in the gradle framework. you can find the source code on my github
