Updating number of points per question in a Quiz (in Storyline)

We have standard quizzes of 5 questions with 20 points for each question, and a passing rate of 80%. I have been asked to update an existing quiz that had 6 questions and will now have 5 questions. However, it looks like 20 points is not being allocated to each question. Where can I find the place where points are added to each question so that I can update it to 20 points per question?
