Class has no link to Column / timetable?

I am new in Gibbon, I found there is no link between class and Column / timetable.
How to take attendance of student and teacher for a specific date and time?
I couldn’t understand the logic. Is anyone can help?

Hi Eric, welcome to the Gibbon community.

The timetable system is what connects the class to the timetable, once you’ve created the structure of your timetable with days and columns, you’ll then timetable classes into the individual periods in the timetable. Be sure to check out our docs here to get started, and give a shout with any questions:
