Actually, one of my fellow OC's got a D and didn't have to pay for it. The money isn't the issue though, I'd be more than happy to re-imburse. My concern is that in the event that I get a D (which is possible because our physics department is out to fail people it seems) whether or not I'll still be able to commission. I'm at the end of my time and can't retake it. I was just hoping that someone would have seen a similar situation at their unit and have some information. If I ask my advisor I'll get the standard answer "Just do your best and aim for a good grade." I'm not a technical major and I'm not going nuke, swo, or pilot. I'm hoping that in the event that I end up with a D that there may be a waiver if a c is required. I appreciate everyone's input and gouge. I amazed at how fast the responses are here.
