IAABO members get a pregame card every year, and it has the NFHS/NCAAM/NCAAW rule differences on it.

It's the only part of the card I pay any attention to.

If I used the card to run my pregame, it would take a considerable amount of time (it's a very long list) and my partner would throw me under the team bus on our way out the door after out game.

Here's the image from the 2017-18 High School Basketball Rules Simplified & Illustrated, note the proper NFHS technique required of the thrower. I believe that IAABO requires the same technique.
