I'm an instructor trying to use the new quiz option to effectively recreate something called JLab. Long story short, it's a 10-item quiz that goes through each option one at a time and provides explanations for the questions. I wanted to set up a canvas quiz to do the same thing for autograding. The idea was for each student to have a completely random set of questions from an item bank, but each student was getting the exact same questions just in different orders. It doesn't matter how many attempts they take, it still gives the same 10 questions from the pool of 26. It's not a matter of the pool being too small, each of the 10 questions is the same for every student.
