I thought it still was but I was certified before the course was split up into itty bitty pieces.
It’s always been the rule with any dive groups I’ve been with from local NJ beach dives up through international trips with D2D and SingleDivers that if you are not comfortable with the situation call the dive and I have never seen anyone belittled for it.
If the rest of the group wants to continue fine but get that diver back to the boat or land first.
