When I was in high school, calculators had just hit the scene. Some teachers allowed them, others didn't.

One of our teachers allowed us to bring a single page of notes to the exam. I wrote my notes on a photocopy of a slide rule. At exam time, I tore the sheet in half.

Of course the teacher thought I was being a smart-ass, and given that the tests were written when calculators were not allowed, they were never really all that useful.

In college chemistry, at each exam, they handed out a sheet that had the periodic table on one side, and a table of logarithms on the other.
