When I was taking electrostatics (over 20 years ago) the class was structured such that if you missed every test but handed in all homework and labs you would pass (barely) but if you only did the labs and test you would fail (even scoring 100 % on every test). Additionally there were two types of tests. Basic tests were every chapter/unit fill in the pencil scanner tests (aka multiple guess) Advanced tests were every other chapter/unit and the answers were required to be in a format termed "3D BE SNUB" by the professors teaching the course. 3D BE SNUB is a mnemonic (which did not survive 20 years of neglect). However, I have found two almost identical explanations of it, one from a HS physics teacher, the other from someone who received it from his HS physics teacher. The sadistic side of me says forbid all electronics. Allow them access to log tables, text book, their own notes (or perhaps a 'cheat sheet' below a specified size) and whatever pen or pencil they want. However, even I wouldn't try this for a survey course.

Irradiated thallium is my favorite weaponized poison. The KGB used it on a number of occasions to assassinate people. This poison combines a number of nasty effects: radiation, chemical poison, hard to detect, no antidote and taking time to kill.
