'Set' numbers and 'Set' letters

Format of Set Labels
You can (optionally) give any lesson a set label.

By default, TimeTabler uses Numbers for labelling 'Sets'.
eg. Maths Set1, Maths Set2, etc.

You can change the labelling to be letters,
eg. Maths SetA, Maths SetB, etc.

Or other styles, or free-format (choose the set labels youself).   To do this, go to Customize Menu->Set Labels.

Timetable Printouts
When it comes to the final Printouts, you can choose (at that stage) different formats for showing the Set number/letter.
eg.  Maths Set 1       or      Maths 1
See Section J9 in the TimeTabler Manual.

Auto-Set shortcut
When editing a lesson in a Batch (or on the Curriculum Diagram) you can click "Auto-Set" in the Wizard, and your groups will be labelled "Set1", "Set2", "Set3", etc.
