Choose Manage → New course. The builder has three parts: an outline on the left, the editor in the middle, and What members see on the right, which updates as you type.

Your draft saves as you type, so you can leave and come back to it.

Quiz
Write each question and its answers, and mark which are correct. Turn on More than one answer is correct for a select-all question. Add feedback for right and wrong answers, so people learn from their mistakes.

Publishing
