I had a biology teacher who would put them into a plywood form and drive a nail through a giant stack of papers.

I don't clearly understand how that is effective, but it sounds like fun, and a good way to impress kids.

She would drive nails through the forms and then count where the marked answer matched the hole. I suspect she got her husband to help too.

It was easy for the students to double check that their tests were marked correctly as well.
