The Quiz activity allows managers to create electronic self-tests using a large variety of question types such as multiple choice, true/false or short answer. The quizzes can can be used to assess the knowledge of the students. The questions are saved in a question bank and are available throughout the whole course room. Quizzes can be configured in a way that students can have multiple attempts. Every attempt will be graded automatically and managers can decide if students will get automatic feedback for their answers and/or if the will be shown the correct answer.
