ABC Order

To help save time when entering grades, my teacher has set up a system of collecting papers. She chooses 5 students who are not close in alphabetical order. So one student from the very first of the alphabet 3 from the middle and one at the end. They are assigned to pick up certain students papers in ABC order. Then they put them all together and in just a matter of seconds the papers are all in order. This makes putting in grades so much easier and it takes less than half the time!
I hope that made sense :)
