Does each testing session and site use different questions from the pools? It may be that we got significantly different chunks taken from the whole.
The exact questions (always from the pre-published pools) are sent to the Volunteer Examiners by the Volunteer Examiner Coordinator(s).
So, for a given exam site, during two different sessions, the questions are very likely to differ.
Back when I was an active VE, I made it a point to schedule two different VECs for the same session. That way, if somebody failed the ARRL exam, they could turn right around and take the W5YI exam. Almost guaranteed to have different questions. Almost guaranteed to cause the applicant to PASS!
