When I was back in school as a nontraditional student, I had huge projects, folders, and assignments due at the end of the school semester. If you have not started on these (and I know many of you are super-organized and have already completed them), consider trying to complete these projects early.
This will actually help you, because sometimes I used to forget one or more parts of my assignments. Having an extra week or so can really help.
BACKUP, BACKUP, BACKUP. I overheard one or more students in the WKU library saying "Oh no! I lost my final report!" They had not made a backup of their work, and they were frantically trying to start from scratch and get their work done on time. Don't put yourself through this. Instead, make a backup or even two of everything you are working on. It's worth the time, and excellent for your peace of mind.
