A few years ago I turned in a friends lab report instead of mine on accident as I forgot I had theirs on my computer. Their's was from a few semesters prior. My professor noticed it first and said this was a conduct violation to have theirs on my computer. She asked me to re-upload my own lab report and find a time to meet with her. I responded offering to meet as soon as possible, and turned in my own lab report. I never heard from her again, never met with her, and the next week ended up receiving my lab report back, getting a decent/ normal grade (no markdown due to the event). I finished the class without my TA or prof ever mentioning it again, and got a passing grade. I am wondering if this is an IA, or how I would find out if this is an IA? If it is not, do I still need to report this?
