TM4T Setting Up Your System 2.1.3.1 - Example Timetable
 Here is the example timetable we've created for you (click image to enlarge).
You may sensibly comment that this is a silly timetable. No free periods for a whole week, then double-frees in Week 2, and several subjects being taught.
You are absolutely right. This has been chosen as a worst-case scenario; hopefully your timetable is much more logical than this one.
