10.15.7. Regarding the Grading of Questions

By setting a default score when creating each question, you can specify the default score that will be assigned when the question is included in a quiz.

After creating questions and adding them to a quiz, you can adjust the point value for each question within that quiz.

How to change the point allocation for each quiz

Click "Questions" in the quiz module.

The point value for each question appears to the right of the question. You can edit this value to set any point value you wish by entering a number.
The "Total score" in the upper-right corner displays the total points for each question in the quiz.
In the "Maximum score" section, you can optionally set the maximum score for this quiz. The maximum score can be set to a value lower than the total score.
Once you've finished configuring the settings, click "Save"
