How to add extra-credit items in a quiz/test? (not 0-point items)

[rdutta]

I also have two urgent questions about the quiz tool:

1. I provide a few extra-credit items on a test and now that I have to do the test online in a hurry, I am not sure how to do this. To explain the issue I am using this as an example. Say, I provide students 6 Questions for a quiz worth 5 points, so ANY 1 item serves as an extra-credit item (not an item chosen by me to have a point value of 0). How do I do that in Canvas? Is it possible to turn a quiz worth 6 points into some other assignment and change the total points to 5 in that assignment while retaining the actual values the students obtained?

(PS: Someone suggested that I make each item worth .833 which cannot work (because if they got 5 of 6 right, instead of getting 5/5 (100%; which is the intent here), they would get (.833 X 5 = 4.17/6 which is 70%).

2.  Having read other similar questions, this is how I am thinking it could work. I give them the Q1 for 6 points. Then create an assignment (with no submission) and call it Q1-Adjusted out of 5 points, and copy the scores over to the new assignment which is set to a point value of 5. Then go back and change the Q1 to an "ungraded survey" or "practice quiz".  Will this work?? I do not want the scores getting counted twice obviously. My understanding is that an ungraded survey disappears as a column in the grade book. Is that accurate? (I don't have a problem if it is so after I have copied the scores).

I have the same/similar question.  I build quizzes with extra possible points, then score out of a lower total score for the exam.  What I did last semester was to build a graded quiz and put it into a separate assignment category that was weighted at 0% for overall points, then transferred the final student scores to the actual exam assignment in my exam category.  That method works, but it's clunky. 

I just discovered yesterday that for graded SURVEYS, it's possible to set a total point value for the survey to determine the number of points students receive when they complete a survey even though internally the survey sets a default point value for each question. I was happy to find this information because it was exactly what I needed to know to set up beginning of semester surveys to replace the paper forms I have asked students to fill in until now.

So, I came back in today to look again to determine whether there was an option to directly set the total points possible for a graded quiz - and there's not, other than manipulating point values of individual questions, which isn't what I want to do.  So, for now, will continue to create two assignments for an exam, so I can assign the points for an exam the way I want to.  I guess another possibility would be to pro-rate the question points to get the desired "total exam points" and regrade the questions during the review to reflect the actual number of points awarded to the student for each question.
