A lot of this comes from professors wanting comments in assinments and grade on arbitrary levels of if it exists.
I had one class where the instructor would give a vuage “not enough comments” that I did comments like this on every fuction and loop out of spite.
That’s kind of what happened to me. Never needed to study in grade school. Had to scramble and learn how to study in college.
Still didn’t register why I had so much trouble focusing or remembering stuff until the last year or so.
