Scenario: Class 10A has Informatics lessons in a computer lab, but the lab can't fit the whole class at once. So the class is split into two subgroups (lab1 and lab2) that attend in separate sessions.

Step 1: Create the division

Go to Classes → 10A → Subgroups → Add division.

Field	Value
Division name	Lab groups
Subgroups	lab1, lab2

Click Save.

Step 2: Add the lessons

Go to Lessons → Quick Add and add:

Teacher	Subject	Groups	Lessons/week
John Smith	Informatics	10A-lab1	1
John Smith	Informatics	10A-lab2	1

Room setup

Assign the computer lab to both lessons. Because both subgroups need the same room, the scheduler will automatically place them in different periods — they can't overlap.

How it looks on the timetable

lab1 and lab2 each get their own Informatics period, both using the computer lab.
