On your first day at Millburn you will get a timetable. This tells you what different classes you will have during the week. It will include both your name and tutor group at the top.
The day is split into 9 periods and your timetable tells you what subject you are meant to be at each and every period. It also tells you which room you will be in and who your teacher is for that period.
The third period is always tutor group time and lasts for 10 mins. All other periods are 40 minutes long but you will sometimes stay at a subject for two of these – called a double period.
