One of the strengths of Studies over studying with traditional flashcards is study scheduling. Studies can take care of tracking which notes you most need to study at any given time, and make those notes due.

You can configure each stack to schedule its notes. To choose a schedule, tap the Edit button in the Library, and then tap the stack you want to schedule.

In the stack settings, tap on Schedule. Choose an option from the list, and enter any additional options that the schedule requires.
