When I taught Composition at a college in Ohio, we were told not to mark with red ink. And that was for COLLEGE STUDENTS!! Of course this was a system where you had the choice of grading papers "Pass" and "No Pass". And some teachers developed more comically arcane grades like "No Pass Plus". If a student failed, or I should say, Did Not Pass the class, they had so many levels of appeal, they could usually move right on.
When I was taking an Oceanography course in college I had a question on a test
"What are sea mounts commonly called?"
Being a smart-ass and also not knowing the correct answer I wrote 'I commonly call them sea mounts"
I was given full credit!
Same test we also had an essay question "Why is the sea salt?"
Again, not knowing the correct answer I replied with a old folktale I had learned as a child regarding a magic mill that would grind out whatever you commanded and the thief who had taken the mill out to sea and commanded it to grind salt without knowing how to turn it off. "
I also received full points for that essay with a note from the teacher saying he remembered this story fondly from his youth
And hence I remain an uneducated moron regarding all matters of oceanography but I have darn good self esteem!!!
