I attended a college where these cheesy foolscap booklets with lined pages and blue covers were universally used in exams where essay questions were involved.
I had one prof who, it was rumored, never opened up those essays but merely carried them upstairs in his house and with one toss of his arm, flung them back into the stairwell to flutter and land as they might.
His wife would then begin at the bottom to pick them up and stack them, beginning with the lowest steps. At some point he would say, "Okay, that’s enough A’s…start a new stack."
And on up the steps.
