I'm working on a doctorate program. I use one of these larger capacity binders each semester to store my coursework. It makes it very easy to pull info from a previous semester; just grab the right binder and you're off! (I do wish they made them in a few more colors though.)
I used it during a preaching engagement...I felt organized professional and prepared...I can use it over and over again. I can also use it to archive the message and not worry about the pages becoming damaged or faded...Excellent product!!
