Hello, I wasn't really sure where to ask this question. I just have a couple questions regarding cheating.
I get this error message when I open up some students' excel files, and I wonder if it's because they have linked to another student's workbook. I've attached the picture of the error message.
Also, I get some files that are saved like Hannah_case1.xls.xlsx
I was wondering if this double .xls.xlsx represents compatibility or if they had a copy of someone's file, and then they saved over it with their "own" work.
