You can open ready-made timetables for classes, teachers, rooms and subjects under "Timetables" in the main menu.
Generally speaking, a timetable window consists of three parts: the details window at the top, the actual timetable in the middle and the period details window at the bottom.
The details window shows various information such as the number of periods per week, unscheduled periods and the time range for which the timetable is valid.
The timetable window shows the actual timetable. You can decide for yourself which information (subjects, rooms, classes etc.) you wish to display and how (font, size etc.).
