This form shows the timetable for a particular teaching group. It opens from the form showing groups for the current academic year (opened by clicking Groups on the Main forms section of the Basics tab of the Timetable Menu) when you click the Timetable button. These records can be amended here or extra lessons can be added, although this should be done with great care since clashes are not automatically shown. You would be better to use the Time Builder application to do this.
