I see a few years back, someone who was rather unhappy with the duplicates received in the box. This question approaches a different form of duplication, however.
Do you ever assign the same element to every student to see how they use it differently to accomplish the assignments? Pull multiple assignments at the same time? Intentionally shuffle previously-encountered assignments or elements back into their respective decks so they'll come back again sooner?
I need to know because of... reasons.
