What's your school's policy for withdrawing? Did you withdraw because you were failing/ going to get a really bad grade?
The way it works at my university - you can drop a class for the first week to 10 days w/ no "penalty", you can withdraw and get a W in the first 6 weeks (approx), and then after that if you withdraw it becomes a WF (whether you're failing or not). So when peoeple have W's on their transcript (at my university) it's usually not because they were failing the class or definitely going to get a bad grade - it's just that the drop period has passed and for whatever reason they want to get out. Yes, their grade might not be great but they still have 6+ weeks to bring it up.
Last fall, our classes started the Tuesday before labor day. I had a class that was only on Monday. So no Monday class the 1st week b/c they started on Tuesday, nomonday class the 2nd week because it was labor day, and by the third monday when I acutally went to the class, hated it, and decided to drop, I had to take a W.
I would just look into your school's policy and whether or not it's a W because you were going to fail.
