Is there a way to add extra credit for a quiz? I see inquiries about such a feature dating back to 2015. I have a quiz with two extra credit questions and I don't want the inclusion of those questions to diminish what constitutes a perfect score.
Not much has changed on this front since the thread in 2015 and classic quizzes are not being developed any more.
If you haven't given the quiz yet, then you can make the extra credit points worth 0 points each. After the quiz has been given, then you can go through and manually grade them to be worth the full points.
If you have already given the quiz, then things become more challenging. You should avoid making changes to a quiz once it's taken.
