An exercise is a part of an assignment, in which you explain what you expect from a student. Exercises can be created, copied and imported. The exercise contains a header in which you give a title to the exercise. This can, for example, be 'Exercise 1', or might contain the subject of the exercise. After the exercise is named, questions can be generated or content can be added.
A question is the part of the exercise which gives a direct assignment to the student. The way students can respond to the question depends on what type of question you ask. Different types of questions can be added. An example of a question is 'What is the definition of a question?' for an open question, or, 'Which of the following options is the definition of a question?' for a multiple-choice question.
Besides questions, you can add content to your exercises. Content can come in the form of plain text, explaining more about the question or giving background information. Also pictures, video and audio can be added.
Note: All exercises need a question in order to give students the ability to score points for this exercise. Only questions can contain points, which can be scored by students.
