My Study Life supports between 2 and 10 days of rotation and also allows you to add classes which occur on both a rotation day and weekday. You can configure week rotation timetables when adding or editing an academic year.
From the general settings screen, you can choose whether you would like the weeks to be displayed as numbers or letters.

From the timetable settings screen, change the mode to Day Rotation and select the number of days of rotation for your timetable. You’ll also need to select which days of the week which apply to the rotation days (the days you attend school).
