In the documentation for this module it says:
Next it is time to add sessions. Note that there is a restriction here. You can only have one session per day. Since you can only have one attendance activity installed (which means that you cannot have a lab attendance activity and a lecture attendance activity) and can only have one attendance session per day, if you have more than one class session per day you will have to be creative in taking attendance."
Is this true? I seem to be able to add more than one session per day.
