Hi @hannaheweinheim ,
To edit the total points the quiz is worth, go to Modules and click the Options icon (three dots) and select Edit. From there, you'll be able to update the points for your quiz. If you have any further questions, feel free to reach out.
@hannaheweinheim , sorry about that! The starting point would be from the Quizzes list, and then the instructions are the same: click on the three dots and select Edit to change the point value for a quiz created in New Quizzes.
