.... Denotes a period of the active lesson
.... Locked period of the active lesson (please refer to chapter 'Locking periods')
x.... Fields marked with a small x are already blocked by the teacher, for instance, teacher Rub is already scheduled to teach class 3a on We-6, which means that lesson 53 with teacher Rub cannot be scheduled for We-6 without creating a clash.
X.... A capital X shows a coupling involving the teacher.
*x*, *X*, *&*..... A marker with two asterisks denotes locked periods creating a conflict (e.g. the PE lesson on Thu-7,8 involving teacher Rub). Locked periods cannot be moved by the automated scheduling tool (see chapter 'Locking periods').
&.... Denotes periods with several unavailable elements (classes and/or teachers).
- 3.... Some periods, in which neither the class nor the teacher are busy, are marked with time requests. -3 indicates that it is not possible to schedule in these periods. The reason for this is that class 1a is blocked due to a time request (see 'Classes | Time requests').
