Sure it could but the same issue is present with one question. Some students will get the wording or find it easy others may not. Having a test in groups to limit cheating is very common and never led to any problems as far as my anecdotal evidence goes.
Thank you for this give away, have a lovely Christmas time, however you celebrate it.
I just enjoy free stuff and don’t have a preference. I sadly don’t have a story to share, well I’ve got plenty but none I am willing to post online ^^
