Have you ever seen someone with a fake college diploma?

Actually you guys could help me with my LinkedIn profile.

I attended X school and got a BA, which is appropriately noted.
I also attended the b-school there (evening program), on track to a full MBA but stopped with 10 of the 20 required courses under my belt once I had my twins. I have lectured there as well on occasion as a guest lecturer.

I haven’t used a resume in years, but when I did, I had something like “Significant coursework in marketing and organizational behavior at X” because I didn’t want to signal that I had a MBA when I didn’t.
On my LinkedIn, though - if I add the b-school, it kind of suggests / implies that I have an MBA, and while I want “credit” for having gone there, I don’t want to misstate that I have an MBA when I don’t. Suggestions? I can put in a “commentary” section - what should I say? I don’t want to mislead, but I don’t want to raise more questions than it answers.
