Yes, they will work it out.
These two pretty much - there are measures in place designed to deal with these occurrences.Even if it initially goes to the wrong place, it'll eventually make it to the right one.
Thats good news, because I did the same thing as the OP :OIf a marker gets a question in front of them that they shouldn't be marking they will take it to their Senior Marker who will take it to the clerical staff and get it relabelled to go to the correct set of markers for that question.
Well, at least there's a few of us who all did the same thingWe were told by our supervisors to write section numbers instead of question numbers...? I initially wrote the specific question numbers but was told to change it...
