I got a zero on a discussion board where my professor accused it of being 100 percent ai. I’m not sure how it got flagged for being 100 percent, I didn’t use ai? It was a short discussion board so maybe it didn’t have enough to work with? What do I do? I feel like I can’t defend myself with it being 100 percent, it makes me look bad. I know these checkers are inaccurate so maybe I could use that to build my case? It wasn’t even an important assignment though so do I just cut my losses?
