Each Section/Assignment is made up of steps.
Notice the names of the steps in the screenshot below:
There are three main types of step:
Question-Answer Step: In this type of step, the system displays a question and the student has to answer it. The step can be categorized as "Practice", Test", "Exam" and "Assessment".
Filter Step: This type of step collects mistakes made in the Question-Answer steps in order to practice, test or examine the students on them.
Theory Step: This type of step is used to display text, pictures videos and other kinds of embedded digital documents to the student.
Notes:
Question-Answer Steps must contain one Stack (that which holds the questions and their answers) and one Drill (that which sets how to display the questions to students and capture their answers).
Filter Steps contain only a Drill.
Theory Steps contain only a Stack.
