I know I saved this. I think a family member might have done something. I'm
taking a course and there are 12 exercises in this .xls file. The longest one
representating over 10 hours to take is now blank. No name, date of test,
just as blank as the instructor sent it. I noted some mistakes that the
teacher had to let the test publisher know about before I submitted it. Now,
this whole test is gone, but the others are there.

I've looked in my recycle bin, other documents are there, but nothing
related to class.

Thanks in advance for any assistance.
