They got rid of paper because teachers are lazy and do not want to spend time grading things by hand.

I’ve spoken to the head of curriculum at a school asking why when given the choice of paper or digital format of a math exam, they picked the digital. I specifically mentioned it’d be inferior as students would not be able to draw atop geometry problems or cross out numbers when simplifying expressions.

The response I got was, “we encourage students to redraw the entire picture on paper as rewriting the entire question is helpful”.

It’s strictly worse. They know it is. And they do not care.
