The course builder is a powerful tool within LearnDash that allows you to create engaging and interactive courses. To use the course builder, start by selecting the course you want to edit from the LearnDash dashboard. Once you’re in the course editor, you can click the “Add New Lesson” button to create a new lesson. Lessons can contain a variety of content types, including videos, text, images, and quizzes. To add a quiz to your lesson, simply select the “Add New Quiz” option from the lesson editor, and choose the type of quiz you want to create. You can customize the quiz settings, such as the number of questions and the passing grade, to suit your needs. To organize your lesson content, add topics to each lesson by clicking the “Add New Topic” button. Topics help to break up the content into smaller, more manageable sections, making it easier for students to absorb the material. With the course builder in LearnDash, you have all the tools you need to create engaging and effective online courses.
