Hello,
Re: Review of question correct/incorrect after each question.
How do I control the review of each question? See the attached screenshot for an example of the review after a question is answered.
I have one quiz where there is a review of each question and I don't know how to turn it off.
I have another quiz where there is no review and I don't know how to turn it on.
I think I have tried all of the quiz settings.
Thanks.

I figured it out. This is controlled by the "show explanation" setting in the "additional settings" tab of the quiz editor.

Hello,

Open "Additional settings" tab on quiz edit page and check "Show correct answers" and "Show explanation" parameters.
