Sorry if I didn't make this clear but not wanting to work on the project doesn't have anything to with the grade in the previous course. Like I said, it is what it is and its not the end of the world. I was actually planning on continuing with the project until I spoke with her a week or so ago about it and for various reasons, she seemed not thrilled with doing it but didn't say she wouldn't.
Also, there are no additional costs or anything like that for the project so it wouldn't be putting her out financially and it was a project I initiated not something she needed help with for her own research so it wouldn't affect her in that way.
As for the experience, I can do a traditional class, which would be along the same lines just not specific to what I wanted to work on. She just hasn't been supportive at all in the past and I don't see that changing this time around. But again I'm worried if this will make her mad.
Anyways, thanks for your help. You make great points.
