Wow, am I glad this question was asked!
When I was a high school senior, I dual-enrolled at the local community college to take calculus classes that my high school didn't offer. I took Calc II my first semester, and signed up for Calc III the second. But being in 2nd semester senior year and realizing that I never would use higher level calculus in my future, I decided to drop the class. Unfortunately, the community college gives you only 6 business days to drop before you get a 'W'. Of course, as a high school senior, I was completely oblivious to this and dropped the class.
So... fast forwad some years later... reading that I would have to submit ALL transcripts from EVERY school I attended prior to graduation, I looked up my unofficial transcript from the community college online to see a big fat 'W' listed (this is when I looked up the "6-day policy").
To put this in perspective, I have never gotten an 'A-' or below since freshman year of high school, I graduated with a 4.37 from high school. And I currently am maintaining a 4.09 (in LSDAC terms) at the University of Michigan (Ann Arbor) Honors College. I work VERY hard to maintain my perfect average. So as one could imagine, I was about to collapse when I read on LSDAC's website that they may count such grades as F's and compute them as 0.00!!! PHEW!!! THANK YOU SO MUCH MURPHEY'S LAW FOR POSTING THIS QUESTION
