Add questions and answers.

Each quiz question has a type, the question itself and its answers. Mix the types to keep a quiz lively.

Steps

In the sidebar, under Content, click Quizzes.
Click Edit in the quiz's row. Its questions open below the settings.
Choose the Question Type first. Each type has its own kind of answer, so changing it clears answers you've already typed (you're asked first).
Type the Question.
Fill in the answers. For Multiple Choice, type every choice under Options, then click the circle beside the right one.
Click + Add Option for more choices. Click × beside a choice to remove it.
If you like, add an Explanation. Visitors see it after they answer, such as why the answer is right.
To take a question out, click Remove beside its number.
Click Save Quiz. You'll see “Quiz updated successfully!”.

Multiple Choice: visitors pick one answer from the Options. Click the circle beside the right one.
True / False: type a statement as the Question, and set Correct Answer to True or False.
Multiple Select: visitors pick every right answer. Under Options (tick the correct ones), tick the box beside each right one.
Slider / Range: visitors slide to a number. Set the Correct Answer (number), the slider's Min and Max, its Step, and a Tolerance (±) for answers close enough to count as right.

Every question needs a question, a correct answer and at least two different options. If one isn't finished, the quiz isn't saved: the question is outlined, with a message saying what it still needs.
Quizzes have up to five questions. Click + Add Question to add one at the bottom; at five it stops working and says “Quizzes have up to 5 questions.”
A quiz made before the limit can have more than five. Its questions are kept, but visitors play only the first five, and you can't add more.
Visitors play the questions in the order they're listed.
