My handwriting has always been terrible. It was a big issue in school until I was able to turn in printed assignments.
Like with a lot of school things, they do a shit thing without thinking about negative effects. They always want a simple solution to a complex problem.
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.
