can I change the points of an online submission assignment?
Yes, you should be able to edit the assignment and change the points value of it. But, if you have already entered scores for students it might be a good idea to print or export those grades before making the change just in case. I'm not sure if the student grades get retained as points or percentages and that is going to affect what happens when you make the change; you might need to re-enter their scores.
