I am new to quizzing w CANVAS. I created some question banks to build an exam. I created a series of banks and then drew samples from them for various sections of the exam. I checked it and tested it and it seemed to be working well. Students have taken the exam and I was surprised to find duplicate questions on the exam. I thought that I must've duped them in the bank and went back to check -- nope. So my question is: When selecting from a bank is it random selection without replacement? If it is, has anyone else had the experience of getting questions duped? My banks are small so, for example, I asked for 6 questions out of a bank of 11 and I saw dupes on the exam for several students. I'd appreciate thoughts from the experts.
