Are these two sentences same?
With the exception of Rob and me, everyone in the class finished the assignment before the teacher came.
With the exception of Rob and me, everyone in the class had finished the assignment before the teacher came.
On searching, I found that "had finished" is the correct usage. Is it because it is followed by "before the teacher came"?
If I remove the "before the teacher came" from the first sentence, to make it-
With the exception of Rob and me, everyone in the class finished the assignment.
will it be (grammatically) correct?
