I got a D on a presentation in college where I presented that patients should fill out the patient paperwork on tablets for easier access and more efficient transfer of patient data.
He said it was a black box solution and it isn’t a real idea.
Top grade went to a group that advised the college to add more paperwork to admission process to make it better.
I almost never recovered from how angry I was with the professor. It wasn’t until later I realized why so many businesses came from dropouts.
