Simple!
Method 1: Say to yourself, “Does my class have FOUR regular lessons this week?” If the answer is “YES” then you have a tutorial period . If the answer is “NO” then you must go to your regular class. (There is the occasional exception – next week, for example, there are no tutorials)
Method 2: Click on the Tutorials button on wgc.school.nz/4Students. Under the timetable you will see a list of times when there are normal classes.
If in doubt, I must find out!
